Pretty much the same for me - ACOT and Scrapbook.com. Will buy some things occassionally at Hobby Lobby (especially like glue/tape I can get at 40% off)
Usually Scrapbook.com and ACOT too. I always check out Michaels and Hobby Lobby but hardly buy from them anymore...I think I have everything they sell. For stamps and dies I buy from My Favorite Things, love their products.
