I tried to make a simple purchase online from Lowes and wanted a courier to pick it up. That session started hours of frustration, phones calls, and wasted time. The cart would show items added, but when opened, it would say your cart is empty. After many retries, the contents would show. Once I eventually had an order completed, I ran into another glitch. They have nothing on the pickup thread to allow courier pickup. After three phone calls, I found out that you have to put the courier's name in my contact info but still use my phone and email. Another kluge!
After three canceled orders and a fourth that continued showing an error, I gave up.
