We all know that buying in bulk or buying 'economy' size packages can often lead to good savings. So, buying the larger refill size containers of cleaning supplies can work the same way. While it might seem more convenient to buy the smaller spray bottle (that usually costs the same amount if not more than the refill), those sprayers rarely work really well or don't last. I've found that it's actually a better value for me to buy sturdier, large, spray bottles at the dollar store and then just use the refill size cleaning solution to fill them up. They last much longer, and as an added bonus, you don't have to worry about what might be in a container. They have different colors so you can choose a different one for each type of cleaning product or you can label them or write on them to tell the difference (instead of having to try to write over a pre-affixed label).
