"Costco is one of the largest contributers to the Democratic Party, particularly to the more socialist/communist leaning candidates."
THAT is precisely WHY I shop at BJ'S or Walmart because they contribute MORE to Republicans. Plus their prices are BETTER.
The Walmart by me is just not that clean, so I can't speak to their prices. But Costco's got better tools, and just better stuff than BJ's. Electronics I'd say is about 50-50. Better to check both places before buying. My wife tells me that BJ's has better every day food, Costco has the better party food.
