APRILFOOLS15
I got an email from Grays Online with this deal.
Spend over $100, get a $20 voucher. However, I'm assuming you can't use that voucher on the purchase you just made. The code expires on the 7th April.
P.S, if you click the link above, it's a part of another April Fools joke they attempted this morning. The deal itself isn't a joke (even though the deal may not be amazing. But good if you were about to buy something on Grays).
Grays Online has bargains?
If you're going to make an April fool's post, at least make it believable…
