The reviews are pretty spot on. SAS does not have AC it has old school swap coolers. It's not AS hot as everyone says it is though.
I have gone into SAS lots of times and have never come out empty handed. Some of the quality does suck. There is lots of stuff to look at. Some of it is really vintage and horribly ugly but some stuff is great!
I have found Alexander Henry fabric here and Nightmare Before Christmas too!
Lace trims, normal trim, elastic, and zippers are all GREAT prices and they have a large selection.
I do recommend shopping here but only if you have the time to dig and walk around. Also You can't be looking for a specific thing because good luck!
The staff has good days and bad days. Sometimes they help you but most of then don;t even sew so they have no idea what you are asking about!
