Just got back from Costco in the SF Bay Area (South San Francisco location) where they had the Briggs & Riley Baseline 22" spinner for $220. Given Costco's inventory practices, possible YMMV here.
This appears to be a model produced specifically for Costco that doesn't expand (Briggs & Riley doesn't make a non-expandable spinner in the Baseline series), but it's a screaming hot deal if expandability doesn't matter to you. Baseline series suitcases start at ~$500.
Still has all the features of Briggs & Riley suitcases, along with the lifetime guarantee.
