Loyalty programme

Every customer who visits our store is enrolled automatically and given a loyalty card. There is nothing to sign up for, nothing to download and nothing to pay. The more you buy with us in a year, the more you save.

How it works

The five tiers

Everyone starts at Bronze. Each tier gives a discount on your bill and cashback that comes back to you as store credit, and the higher you go, the more you get.

These are sample cards: your own card carries your personal four-character code. The discount is taken off your bill before GST. Cashback is earned on what you pay, GST included.

How your tier is decided

• Your loyalty year is the twelve months from the day you joined. What you spend in it decides your tier.
• Your spending is the total of your invoices in the year (after your discount, with GST), less anything you return.
• You move up the moment your spending reaches the next tier, even by more than one step. The bill that takes you over the line is still worked out at your old tier; the new tier starts with your next purchase.
• At the end of your year you keep your tier if you spent what it asks for. If not, you move down one step. Bronze is never taken away.
• After that your twelve months start again from nothing.

An example

A Gold member buys goods billed at ₹10,000

Bill before discount	₹10,000
Gold discount (6%)	−₹600
Price after discount	₹9,400
GST (18%)	+₹1,692
You pay	₹11,092
Cashback (3% of what you pay)	₹332.76 of store credit
Counted towards your year's spending	₹11,092

The figures are an illustration. Every bill is worked out at the counter on the day, and each amount is rounded to the paisa.

Your store credit

• Store credit is added to your account when a purchase is recorded, and you can use it on any later purchase in our store, in part or in full.
• It can pay for the GST as well as the goods, and there is no limit to how much of a bill it can pay.
• It has no cash value: it cannot be exchanged for cash or passed to someone else.
• It does not expire at present.

Terms and conditions

Last updated: 3 November 2026

By using your loyalty card or accepting a discount or cashback, you agree to these terms. They are issued by Diamond Electrical Industries, Kolkata ("we", "us", "our").

1. Joining

Every customer who visits our store is enrolled in the programme automatically, and a card is issued to you at the counter. Membership is free, with no form to fill in and no minimum purchase. We ask only for your name, and for your phone number if you wish to give it. Your Bronze benefits apply from your first purchase.

2. Your card

Your card carries a personal four-character code that is how we find your account. Show the card, or tell us your name or phone number, when you buy. Please keep it safe: if you lose it, tell us and we will issue you a new one.

The card remains the property of Diamond Electrical Industries and has no cash value. Membership is personal to you: your tier, discount and store credit may not be sold, shared or transferred to anyone else.

3. Where it applies

The programme applies to purchases made in person at our store. Orders placed online on dewdiamond.com are not part of the programme at present.

4. Discount

The discount of your tier is taken off your bill at the counter, before GST. It is worked out on the price of the goods and applies automatically.

We may sometimes agree a special price with you, for example on clearance goods or a project order. Where we do, that price applies to that purchase in place of the tier discount, and our team will tell you before you buy.

5. Cashback

Cashback is a percentage of the amount you actually pay on an invoice, GST included. It is not earned on the part of a bill you pay with store credit. It is added to your account as store credit when the purchase is recorded.

6. Store credit

• Store credit can be used on any later purchase in our store, in part or in full, and can pay for GST as well as the goods.
• It has no cash value and cannot be exchanged for cash or transferred to another person.
• At present it does not expire.
• While your store credit is below zero (see Returns) it cannot be used.

7. Spending and tiers

Your loyalty year runs for twelve months from the day you joined. Your spending in it is the total of your invoices (after the discount, with GST), less anything you return.

• You move up to a higher tier as soon as your spending in the year reaches the amount for it. The purchase that takes you over the line is billed at your earlier tier's rates, and the new tier applies from your next purchase.
• At the end of your year you keep your tier if you spent what it asks for. If you did not, you move down one step. Bronze is never taken away.
• Your twelve months then start again, counting from nothing.
• We may also place a member in a tier by hand, at our discretion.

8. Returns and exchanges

Returns and exchanges are governed by our Refund Policy. When you return part or all of a purchase, the discount, the cashback and the spending that belonged to that part are taken back in the same proportion as the goods. Store credit you used to pay for the returned goods goes back to your account.

If the cashback that has to be taken back has already been spent, your store credit balance goes below zero. The cashback on your next purchases clears it, and you cannot use store credit until it has. Your tier is not changed by a return; it is looked at when your year ends.

9. Misuse and mistakes

We may correct any mistake in a record, and we may refuse, suspend or end the membership of anyone who misuses the programme, for example by giving false information, tampering with or sharing a card or store credit, or abusing returns.

10. Your details

We keep your name, your phone number (if you give one) and your purchases in the programme so that we can work out your tier, discount and store credit. Only our team can see them, and we do not sell them. Our Privacy Policy explains how we handle personal information.

You can ask us at any time to show you your details or to delete them. If we delete them, your tier and your store credit are lost.

11. Changes to the programme

We may change, pause or end the programme, or these terms, at any time. The latest version is always on this page, with the date it was last updated. A change applies to purchases made after it.

12. Governing law

These terms are governed by the laws of India, and any dispute is subject to the courts in Kolkata, West Bengal. Please read them with our Terms of Service.
