I am the occasional Marshall's shopper and it is always exciting to find some stuff in the store (depending on the day you go). The prices are just right, but sometimes the stores seem like they were hit by a hurricane. Must have something to do with people rifling through all their stuff looking for the best bargains.
This Marshall's at Rivergate is a standard Marshall's. Relatively clean, I was able to find what I was looking for in the Men's department without any issues. I do like their register: "[robotic voice] Register 3 is now open" system... makes for a clean and easy check out experience with the exception of them funneling you through a row of shelves with a bunch of impulse buys on them.
Not a big fan of the parking lot, but the prime spaces are the handicap spaces and then everyone else jockying for position to do the least amount of walking to the building.
