Hello and welcome to the wonderful world of beading! I also buy beas at the above mentioned sites but use etsy and ebay for beads and findings. On ebay search listing for bead lots and on etsy search bead destash. Different terms, same concept. Many people are liquidating now after the first of the year. You can get a huge lot of mixed items and then use what you like and resell or donate the rest or pass it on to other beader friends like I do! I also used to participate in beader swaps with people on boards like this, I believe there was one on here in the hobbies forum. It was a fun way to get rid of some of the things you bought and never used or something you have left over. Feel free to PM me for info! Welcome to the craft! Missy
