sorry....didn't notice your other question....
www.strapworks.com has great prices on purse parts. What I like is that they don't charge a flat shipping rate - they go buy postage weight which is nice if you only need a few things.
I had a problem with a set of clasps I bought - turned out to be a bad batch. Called customer service and they refunded my money without question and provided a return shipping label so there was no cost to me.
There are a couple on ebay too but don't remember them right now. If you still need their info, PM and I'll try to find them.
