One of the freebies I've mentioned before are samples. You may think that they are not worth your time to get a one-use sample of something but they really do come in handy.
While traveling recently, I used sample sizes of deodorant, shampoo, conditioner, toothpaste, dental floss, and wipes. That was just on one trip. It made my packing easier, I didn't have to worry about the correct sizes for security, and when the sample was gone, I threw it away. I didn't have to worry about packing empty bottles to take home to refill.
Not traveling? They are still useful! Do you have an overnight guest on the way? Pick up a small basket at a dollar store and fill it with sample sizes of various things they'll need during their stay. You can also pick up a small washcloth to use as a liner for the basket. Include a few different brands of shampoo, etc. to suit whatever need they may have. It never fails that you forget to pack something and you'll be ready to fill their need.
Free samples coming in mean less money going out. Say that you purchase a bottle of shampoo for $4.00. You get 20 uses out of the bottle. That's 20 cents per use. Using a sample of shampoo you received then saves you that same 20 cents. Is it a fortune saved? No. Does it still save you money? Yep!!
Samples are available all over the internet. Check the webpages of your favorite brands and follow them on Facebook. Target, Walmart, Costco, and Sam's Club also offer samples. For the investment of just a few minutes of your time, you can save money and have products you need.
