On the one hand the normal grocery stores around me have better availability. Even now it’s running thin but I would start there and branch out. It seems like everyone goes to
Walmart and warehouse stores, then Target, then the more expensive places. Heck my local grocery store still had a couple packs of TP and water bottles yesterday (but the manager told she has no idea when the next TP shipment is coming in). Admittedly we are about 3-7 days behind whatever craze hits American shoppers.
Our Costco on the other hand had a darn near stampede over water bottles last weekend when a shipment arrived on a Sat afternoon. The story is all around town, it was a thing- heckuva time to be working at Costco I guess! Any of those hundreds of people could have paid $1-2 more and bought bottles at the local grocery store without risk life and limb and shoving their carts into others to get there (legit that’s what was reported happened) but they’re buying from where they always buy (Costco) and not thinking outside of the box.
Also, if you have to start driving far out consider mapping out a plan of store attack and you can always try calling ahead to see if it s even there before you try to grab it. The supply chain will catch up though! ...DH could always try to chat with your local store managers about his pregnant wife and see if he can find out when next shipments are expected...
