My mom bought my dad one for christmas a few years ago. Got it from Dicks as they had the cheapest price by about $30.
Noticed after he opened it that it only came with a Modified choke tube.
Checked with dicks, and that's how the guns are sold there, but they would be happy to sell me the other chokes...
So we just spent about $50 buying 2 remchokes and a choke wrench for his birthday. (Bought them online, much higher price at dicks)
So if the option of different chokes is something you really want, then you may want to look elsewhere.
Not sure what walmart offers, but know my local gunshops offer them with full, mod, & improved tubes.
The quality of the gun itself is fine, heard several times the myth/urban legend that walmart, dicks, etc get the crappy guns that don't pass the inspection for the actual gun shops. It's bull from my experience, most of the time passed on by shop owners to get people to buy from them.
You shouldn't worry about that, just check what accessories you're getting with the as many of the big box stores cut some corners there to increase profits.
