Self Checkout

Because I got tired of incompetents screwing up my curbside orders.
I've been making weekly delivery orders for 4+ years now in CA, AZ, TX, LA, etc and I can count on one hand the number of times an order has been screwed up. Even then, it's still more efficient and hassle-free than going into stores to shop.

because I never really know what groceries I'm getting until I'm looking at them..
You don't know what you ordered?
