This is a consumer protection issue. You may be old enough to remember, but retailers routinely would mark items as being a certain percentage off, but the item would never ever sell for what the retailer was saying its regular price was. Consumer protection laws were then passed (at leas in California) that said that at some point the item had to sell for a regular price if the retailer was going to mark it as selling for that price. This is why you will see some sites , like monoprice, use the term "compare at price" rather than regular price.
MSRP means something. I'm not at my computer now, so I cannot look up the consumer law, but MassDrop is a retail establishment and they are being dis entice to their average consumer when they suggest something regularly sells for more than it does, only to then show a false and inflated discount rate. MassDrop should simply change the term MSRP to Compare At and they would be less deceptive.
As for MassDrop needing to research actual MSRP, yes, they should. It's not that much work, and if they post incorrect information that falsely inflates their posted discount rate, that is deceptive. It important for folks in this deal forum to understand that, so I feel it's relevant for this thread.
One more note. A number of counties in California sues Overstock for this very issue, and won. Overstock is appealing the $6M+ award against it. http://www.wired.com/2014/01/overstock-price-ruling/
