This has been a head-spinning week for fans of carmaker Tesla, which announced plans to close all of its retail stores last Thursday and reversed that decision a few days later. Tesla now says it will keep most of its stores after all, including the one at Westfield Montgomery mall. Meanwhile, the Invisalign orthodontic chain is unexpectedly closing all its stores for real. The decision comes after a legal battle with a competitor, SmileDirectClub, which accused Invisalign of violating a non-compete agreement between the two companies. Arbitrators agreed with SmileDirectClub. All Invisalign stores, including the one at Westfield Montgomery, will be gone by April 3rd.
