1-2 hours x 6 days is still lots of time!
I can think of a few different approaches:
1) go through your last orders, and depending on how prolific a shopper you are, either make a list of the last 10 orders, or maybe the last 3 months of kits. This way, you know you have a quick and easy stash of kits to pull from that should be current. (I know The Committed Crafter is retiring, but I'm not positive when.)
2) If you are more of a favorite scrapper: Make a folder and copy (not move) your favorites. Add in a few staples, some stitches, some flowers, some generic word art, some basic papers - neutrals and your favorite colors, maybe a frame or two. This depends on what your favorite go-to products are. This takes a little longer, but I would also make sure they are current in the store. This lets you easily grab from this folder without worrying about the 75% current product since you know it is! If a challenge calls for something, let's say a mask, that you didn't put in your folder, it'll be easy to just go find that one thing.
3) What are your fullest kits that you adore? I know you subscribe to Storyteller, and you might have a collab or two. Check to make sure they are in the store (most collabs are, and I know a lot of the Storytellers are!), and pull a preview shortcut into a folder. This is best if you are a one-kit scrapper or like to color match your photos and kits. Then, you can look at this folder to find a kit to use. Click the shortcut, and you are right to the kit!
You should be able to pull together these in minimal time. Don't worry about getting every item since you know you won't use them all. This is more to give you a quick starting point.
