Thankfully they offten have different items -- and different brands -- in the stores.
Also good that the stores carry 2 wheeled luggage. Spinners are great for a slow stroll through an airport, not so great for use on the streets (or worse over cobblestones, bumpy pathways, etc.) or if you are in a hurry and want to move quickly.
Frustrated by the "if two is good, four has to be better" mentality.
