Like the swallows that return to Capistrano and the inevitable taxes we pay every April 15th, the mall Halloween pop-up store has become an annual ritual. Not associated exclusively with holidays, pop-ups can mean quick and easy income from the increased foot traffic in prime but previously unused space. Tom Jones, principal with Colliers International, recently told the Albuquerque Business Journal that Halloween store deals are great for landlords for several reasons. “One, the store occupies space and pays rent for a couple months. Secondly, the landlord doesn’t have to kick in any tenant improvements, because the store typically does their own setup.” So when will we see pop-up stores for Valentine’s Day? What holiday or time of year is most likely to see a successful pop-up store?
