It's very rare to go to this Walmart without spending more time in the checkout line than actually shopping. That's not even an exageration... well, maybe it is slightly but I routinely plan on spending at least 15 minutes even in the "express" lanes.
It's a good thing they built all of those checkout lines... so they can use them 2 times every year (black Friday and for Christmas season).
Wandering around with an "I am so lost and can't find what I'm looking for" look on your face will never help. You have to be proactive since nobody ever asks if they can help you find something.
Overall, it's a good Walmart with a nice new (for now) facility that is very convenient.
