Another ebay shop is having a sale. They have Frances Meyer sticker sheets listed at between 5 and 20p, but they all have Best Offer availability, and it seems to be set to automatically accept offers of 1p. The maximum postage anywhere in the world is �2, which I think is about $5, but if you buy a lot of the sticker sheets it works out great.
I bought about 15 sheets at the listed price, and then I noticed that someone had had an offer of 1p accepted, so I decided to give it a go. And I ended up buying a lot of stickers, and then a couple of button grab bags, just because I felt slightly guilty about all the 1p sticker sheets I'd ordered. :P
Anyway, I haven't ordered from here before, but they have 100% positive feedback and more than 15,000 feedback received, so I thought someone else might be interested, and it seemed like a good deal to me
