I recently bought one at Costco with my Costco rewards it came with a bunch of bags but I bought a huge refill also at Costco just in case. This was all right before the COVID-19 hit and everyone went into lockdown. The wife and I buy meat in bulk from Costco and then separate it into smaller usable portions and vacuum seal it. It takes a little time after getting back from the store to sort it all out, weigh it, seal it, and label it but it’s worth it. I would recommend the name brand Foodsaver but that is only because it is the only brand I have used and it works great for me. I am not familiar with any other brands. I hope this helps.
