Imo, Petsmart has a better quality control than Petco but I have purchased bp's from both. I bought a pastel 0.1 from Petco and she was healthy, bought a 0.1 normal from Petsmart also healthy. I have had them both about a year now and they are great feeders. Both purchased as approx. 3 mos. old young babies. Absolutely no health issues so far. I did overpay for the pastel, but made up for it with the normal. Actually they both are pushing the 600 gm weight now and will be 1 year old in June.
