I would like to propose an initial year long period for listings to stay live in the UK market, and some kind of staggered expiration of those products that were automatically added to those marketplaces. Given the newness of those markets, and their relatively small size compared to the U.S., products need a longer time to catch on.
Looking at my own dashboard, I am about to be faced with an absolute flood of expiring products that were moved automatically into the UK and German markets. Currently I see very little motivation to spend time relisting those products - other than just selected few - because my returns are much lower there than in the U.S.. This is especially so since it takes extra time to list in German for that market. I believe at least for this first year, extending the product life would be of benefit to all.
