Some things.
Rules of bulk buying-
If you aren't going to eat an item by the expiration and have 50 of the item don't buy.Buy individually or what's needed.
If you have no place to store certain items don't buy. 50 rolls of toliet paper may be useful but having them sit in the bathroom where moisture can get to them is not.
Some stores still offer sales on one item.So, buying 3 or 4 only to get a sale price may not be needed. (unless of course they are like bath and body works and you need to buy all for the sale price)
See if you can share the bulk items and split the cost. If you have a family member who is willing to pay half and you can split the items you make out even better.
It really does help though at times.You pay for conviance.So one portion of chicken can be higher then buying a pack and freezing the rest.As much as I hate it I've been buying boneless skinless chicken breast and cutting the fatty part off because I realized how much money I was wasting every week on packs that we could only get 2-3 meals out of and partly because I hate taking the time to cut the fat and well...it's gross.But I paid more for the 94% fat free and the look of no fat.
