Instructions:I made an order from FunkyHampers.com yesterday, and today they've emailed me a handy promo code. It is for £3 discount, and it doesn't seem to have a min spend.
E.g. I tried it on a £6.99 chocolate box, and it worked.
Standard shipping on orders under £29.99 is only £1.99, so at least it covers that if you're only making a small order.
Be sure to look in the HUKD voucher section before you buy though - there are other voucher codes in there which might get you more discount depending on exactly how much you intent to spend.
