It seems like I've been shopping at Walmart all my life.  They are rather ubiquitous here.  They do have more than 11,700 stores.
I've shopped at Walmart a majority of my life too! Though, now that I've moved cities I tend to shop at HEB for most of my groceries, but they don't have other random items that I'll need so I've relied on Amazon to get those things!
Walmart is a little rough these days though.  Most of the stores around here aren't very well maintained and it seems to be deliberate as Walmart tries to cut labor costs even more than they already have
Walmart and Amazon both share the same goal, which is to increase profits and keep customers happy while they underpay their employees and treat them terribly in my opinion.
True, although Amazon does pay more than Walmart, they also seem to work them harder.  You'd think both of these companies, with the largest revenues in retail, could spare some money for their employees.
Yeah, the worst part is that in order to keep customer retention they give customers discounts/gift cards when they are dissatisfied but the workers get nothing especially when working conditions are extremely taxing on the body and mind.
Criticism of Walmart
Walmart has been criticized by groups and individuals, including labor unions and small-town advocates protesting against Walmart policies and business practices and their effects. Criticisms include charges of racial and gender discrimination, foreign product sourcing, treatment of product suppliers, environmental practices, the use of public subsidies, and the company's spying on its employees. Walmart denies any wrongdoing and says that low prices are the result of efficiency.
In 2005, labor unions created new organizations and websites to criticize the company, including
am taking a break from being told what to do. ... It's cool when you look at someone and don't know whether they are at work or play since it's all the same to them. The things I've been doing for work lately have been so much fun, because it's not like work to me anymore. I've been even more 'hands on' in my management and the business side of things, and I feel more in control than ever.
