All the time. They drive me crazy - and I drive me crazy, continuing to shop there despite the issues. I swear, I've returned more things to TJs than to all other groceries combined in my entire life.
Their organic hummus is fabulous - since tasting it, it is now the only hummus my kids will eat. But it ferments (and swells the package and in a few instances has exploded the package) well before it's expiration date. Sometimes the packages are already swelling on the shelf! I've returned several cartons of this hummus already for this problem, and have thrown away several more because I wasn't getting to TJs anytime soon. I continue to buy it, but try to get the girls to eat it very quickly.
Cheese - I've had their cheeses go moldy within two days of getting home.
Produce - I've bought raspberries, taken them straight to the park to eat with a picnic lunch, and found them moldy all through the center. Moldy artichoke hearts. Greens that have wilted in no time flat. Avocados that are so bruised they're unusable. Yep, I've returned most of these things, though a few were waste because I didn't plan on getting back there soon and wasn't keeping moldy fruit in my fridge for two weeks.
Jar of jelly - went to open it and found the seal was already popped; the jelly was moldy on top. How freakin' long does jelly have to be open to go moldy? I have kept jelly on my countertop for days with no problems! Candied ginger - bought a bag, and they tasted naaasty, don't know what was wrong with them. Gluten-free cookies - found bag to be unsealed.
Meat - several times I've had their meats smell funky well before expiration dates. The worst is hot dogs, because I'll open the pack, use a few and put the rest in the fridge for a later meal. I come back for them and they smell funky, but it's days or weeks before the expiration date. They sell the same brand of organic, nitrate-free dogs as my local hfs but for about $1 cheaper per pack. Now, I usually opt to buy locally, but at that discount... I've given in to temptation a few times when I'm there. But no longer - it's no discount if I have to throw away half the package!
The only thing that keeps me going back is their no-questions-asked return policy. In fact, they're so cool about returns that they don't even ask for a reason for record. I've had to push them a couple of times to let me complain about whatever was wrong with the item
