You can spend a lot of money keeping the bathroom stocked with essentials. But if you don't need to have a name brand, you just may find that the personal care aisle at the dollar store has many quality products that will do the job just as well. Again, please check prices in your area.
1. Band-Aids. For years I tried different store brands in an effort to save money. The individual strips were hard to open and the plastic was of such a poor quality that it would tear. I had all but given up when I discovered Medi-Care at my local dollar store. They are sterile, open easily and stay put. My store has them in packages of 60 regular or clear, five large size and children's cartoon designs. Johnston and Johnston bandages cost $3.27 for a package of 40 or a package of 10 large. The larger, patch type band-aids are 20 cents each at the dollar store. The brand-name ones, at the price I saw, would be about 33 cents each. The off-brands won't "cling in soapy suds" but under normal circumstances, they do the job very nicely, thank-you.
2. Purell hand sanitizer cost $4.87 for 237 ml bottle with a pump. The dollar store brand comes in a 236 ml. pump bottle for $3.87 less.
