I think selection varies from store to store. I heard about some M's have Basic Grey paper packs, but I have not seen it at my local store. At mine, the "newer" things I saw are Prima flowers and some paper packs, Making Memories Passport collection (papers, embellishments, etc), Martha punches - some new ones, Hero Arts stamps - not the more recent ones, but an improvement, and Changito and Fluffles stamps.
Martha has all Halloween punches, papers, craft kits. The ribbons were on sale.
Hopefully you can also find Joann's and ACM nearby!
You might find the lunchbox tins and other alterables as well.
Look for the 20% off total purchase coupon as well. Have fun!
