I have been a Blick customer for years, but lately I avoid them if at all possible. Between their slow processing time (2 - 3 days) and terrible shipping (FedEx DumbPost) service, I've pretty much had it with them. I live in Florida and it takes, on average, 9 days to receive my order. Sure I could spend another $3 on the "upgraded" shipping, but even then my order doesn't arrive in a timely manner.
On top of that, when you check out, your cart says that your items are "in stock and reserved" This is a load of bs. I ordered 2 of one item and am only being shipped one despite the "in stock" message.
I prefer Jerry's Artarama, but sadly they do not carry some of the things I need. I suppose I will continue to deal with Blick's lousy shipping and processing time whenever I need specific things
