Well there is a logical reason for MAP or Minimum Advertised Price,, It makes sure a retailer that is willing to sell for pennies over cost doesn't drive away all the other potential retailers from buying from the distributor or manufacturer. This way a manufacturer has a broader reach other than just one retailer monopolizing a product line. If a guy knows Joe down the street has already cornered the market he'd never order product.
Same reason many ads in magazines say "call for price",, if they posted the MAP, which is the lowest price the can,, you'd never call,, most often the "street price" is below the MAP.
What erks me more is having to create an account to calculate shipping cost,, that's BS
Not sure how having a lower price when it goes in the basket is a scam though??
