customholds sells via ebay as well as via their website usually substantially cheaper too! #
between me and one or 2 others we have had a few sets from them through ebay.
fantastic service and the guy is friendly and products are very good, and he will also sell you bolts and t-nuts at a competitive price!
An italian guy sometimes also sells on ebay, selling sets of 50 screw ons which are good for crimps and footholds, again, despite being in italy they arrived quickly and are quite impressive too.
hope that helps
