These are $1.00 apiece on the LiveStrong website - you buy in 10 pak bundles (or 100 or 1200) and do have to pay shipping (that amount differs depending on where you live). Might be a good idea to buy a pak and give to friends, or sell them and send any profit back to the foundation to help their cause or just buy more bracelets. I put in an order for 20 and total price (shipping & tax included) came out to $29.50 ---> which would be $1.48 per bracelet --- not bad at all!!
