Worst: Disposable Razors
Buying a big box of disposable razors at Costco may seem like a good idea, but did you know the prices at Walmart are actually better than Costco? At Costco you can find a pack of Kirkland razors for around $23. Therefore each razor will cost approximately $1.64. Walmart on the other hand offers a pack of 10 Gillette razors for $7.97, which is $0.80 per razor. You can make great savings and even get a better brand.
Buy: Uncooked Cookies
Everyone knows that you can buy desserts at Costco but have you ever considered buying uncooked desserts? Like pastries and cookies? If you want the same product but want to save shedloads of money, simply go to the bakery counter and request a box of uncooked cookies. Save significantly as you can get a box of 120 pieces for $22.99, whereas a box of cooked cookies (21 piece) will set you back $7.99. This is a great saving indeed. A little work will work out much better in the long term.
