Mattresses make me wonder if, stupidly assuming the rule is enacted and enforced, there might be knock-on effects. TVs, mattresses, electronics, etc like to sell distinguishing SKUs to different platforms. That is, Target may get to sell the Sony 59" ABC123, but Walmart only ever gets the Sony 59" ABC456. Rendering it impossible to get stores to price match products from other marketplaces. Big if, but if these rules go into effect, I wonder if maybe reviews being harder to solicit could result in more consolidation of model numbers to concentrate the review scores?
