Lines are always very long and I've returned home with home containers on more than one occasion. Granted, that's more customers than the company -- but to return/exchange I need to sit in a long line since only 1 lane handles this issue, and it's a 1-10 item lane -- which means I have to stand in line twice if I want to also purchase groceries. I end up just throwing out the opened items instead. Money in the trash, but less headache.
If you have a car just drive over the to Lawrence/Victoria Park location -- it's a better store when it comes to pretty much everything.
