Hi, I've seen the Cinderella slippers that are very reasonable. I've got some for our guests (we are in the UK and they were from a UK supplier) and they are really good. Ours are decorated with beads and roses and they will have bath petals in them. Here's a picture:
There are usually quite a few on ebay, but what would have stung me was the postage to the UK so I bought them here.
We've also got these:
and they are gorgeous. I've seen these on ebay and other websites too.
I got these crystal slippers to give to guests and to people who couldn't make it to the wedding as a keepsake:
and they are about $3.00. I wish they were that cost in the UK
We ordered from Ebay packs of gum that were personalized with the slipper and shoe like your avitar it said "Happily Ever After" Amanda and Eric and the date. We received 20 packs of gum for less than $15.00. we put them in the welcome bags for our guests. I will get Amanda to take a pic and try to post it for you.
