New Massachusetts state regulations taking effect tomorrow will allow stores to stop stamping prices on their products. Instead, stores can set up price check scanners for consumers to check the prices of products themselves.

A convenience or a pain in the butt? I think deciding on a purchase is often just as much about the product as it is about the price. My guess is that many of those impulse buys might just fly out the door.

Not surprisingly, big chains like Wal-Mart are jumping at this, installing the scanners in every 5,000 square feet of their stores. Retailers say the new regulations will save them money in labor costs, even though the scanners can cost as much as $1200. Will smaller retailers be jumping at the chance to install these scanners to reduce labor costs? Are the scanners really worth the inconvenience to consumers?
