One of my worst performing apps I use on a constant basis. Never seems to register my payment or when I select free delivery it never gets deliverdd and continuously mixes up the meds I need versus meds our Dr discontinued. Thankfully I only live 3 miles from Walgreens so I most often need to physically go to the store to straighten things out. Going to the store is much faster then waiting through phone communications. After 8 back surgeries, this not convenient for me. Please do better.
