I already know that most people get their bags from Cornerstone Farm but I was wondering if the shrink bags on Ebay would serve the same purpose. I converted their thickness and compared it to Cornerstones and they are thinner but I wonder if they would still work and freeze well. The cost for the bags is much more reasonable. I am not trying to shortcut on quality but I was just wondering if anyone else has experimented with these bags and if so, what are your recommendations. My meaties are still only two weeks old so I have a little time to decide what to purchase. Thanks in advance.
