I really have a hard time imagining that a company the size of midway will get involved in petty little schemes like bait and switch.
There is very little to be gained by conning your customers, and you stand to lose many, many dollars of future revenue. Besides that, let's be serious. a business can find hundreds of ways to legitimately screw their customers, over and over, right out in front of god and everyone, and make a few extra dollars on the majority of sales. Some places pad shipping. some use gimmicked auctions or sales. Lots of companies even have multiple virtual storefronts that operate with the same inventory out of the same warehouse, with no significant differences other than price schedules.
A company like midway could create a subsidiary called, for example "cheap doggoned ammo" selling ammo for 10-20% less than midway pricing, and operate both companies out of the same facility, shipping with different labels and invoices. They would be able to exploit the cheapskate market, while exploiting the full price market, and heck, maybe even have a premium ammo company called "safari grade shootin arn fodder" that sells the same darned stuff at a 20% increase, all out of the same facility.
a good company, a good product, and a good business model of that size doesn't need to cheat the customers. The only smart thing to do is make sure that the customer keeps coming back. YOu want to see someone screwing the customer? Look for a business that turns less than $100,000 a year in sales. Sticking your thumb on the scale in a business situation like that will make a big difference every day. a company like midway, amazon, so forth, would need an enormous fraud going on to make a difference.
