Greetings,
Mouser is definitely cheaper these days, didn't used to be. They've also added THAT components as a distributor, so you can get VCAs from them. I've also found Arrow Electronics to be a inexpensive source for some things, they have a much more limited range of components, but what they do have is nicely priced. Great for me as standard shipping is FedEx and its two days ground from Reno Nevada to Portland Oregon.
