Ironhalo.net are offering a discount to clients who refer new customers to their online store.
From their announcement:
Announcing the Ironhalo.net Who do you know? Promotion.
We believe word of mouth is one of the best ways to promote any business, so we want to reward people who send thier friends to our site.
So until the end of September we are doing the following:
If you are a new customer and make your first order from our online store, put the name of the friend who told you about us in the comments section when you check out.
If they are an existing customer we will give them a voucher for 20% of the value of your order (not including postage), and we will give you a voucher for 10% of the order as well, which you can both use for future orders.
So if you have ordered from us before, tell your friends, if you have not, find someone who has. And sorry, you cannot use one of our retailers as your referrer.
