I find I work more/longer hours when I work from home - likely because of the guilt I feel for not coming into the office, but also because instead of spending 2 hours commuting to and from the office, I can use that time to work instead.
@Christina R Here's my guess - they have very limited hours. They close at 6PM on weekends - crazy! Plus this is one store you want to avoid at peak hours, it can get maddening when all the samples come out, people just kind of hang out at the end of the aisles and they're really annoying to get around. But if you're CostCo, you want people to be hanging out sampling your product so I can't really blame 'em.
Exclusive, you missed exclusive! While it may sound silly, one of the main reasons I shop at CostCo is because they carry brands/items not available anywhere else. I crave the Morningstar Spicy Black Bean Burgers that can only be found at CostCo - as well as the Disney brand animal crackers...
