Sam' s club opens @ 9:00 for retailers and 10:00 for the general public.
10:00 am on Sundays. No special hours that day. I highly recommend downloading the Sam's Club app, as well as the Scan and Go app. You can scan items as you put them into your cart, pay at the touch of a button, show your phone on your way out the door, and stores all of your receipts. Gets you out much quicker.
The Google maps link info states 10AM, but I think if you have the pricier Advantage membership, you can get in an hour earlier.
I think 8;30
