I shop Hobby Lobby when they have: Paper packs 50%, because they carry some Basic Grey and other better quality brands. 50% off "Paper Studio embellishments." That's their store brand, and it's a good time to get brads, bling, flowers, etc.
I shop JoAnn's for: Cricut blades & mats because they're the only ones that take coupons for them. Paper sales, they stock some Disney single sheet paper. It won't be 5/$1 because they are more expensive, but it will be at a discount.
I will shop Michaels for: Cricut cartridges. Their BF and around Easter prices will be cheaper than the other big box stores (although online will be even cheaper), storage like Jetmax and Iris, and I will use their coupons for adhesive. Also, they will put their store brand "Recollections" stuff at 50% from time to time. So brads, stickers, flowers.
JoAnn's will also often have 40% off just about everything, 30% off Disney. Hobby Lobby, I think sometimes has discounts on "3D embellishments" so that would be for the Jolee's and EK Success fancier Disney stickers.
