I used to buy 1000 t-shirt bags in Costco and BJ, last time I bought them in 2019 and the quality was great, I run out of the bags just recently and again ordered a box of 1000 from BJ in March 2023 - it's unbelievable how the quality got so much worse! They were awful, thin and tear extremely easily, not worth anything. Then again I ordered bags on eBay, advertised as heavy duty - same thing, poor quality and unusable. Although full of doubts that good quality bags exist out there, I made a third attempt this year and ordered here these t-shirt bags on Amazon (the ones with that purple rose print) and I'm pleasantly surprised, they are as good as they could be - big size, thick material, heavy duty, not a single thing I could complaint about, besides the price - yes, they are not cheap, but they're definitely worth it. I highly recommend.
