When the airlines restricted your ability to bring liquids on planes, Clark started going to the dollar stores wherever he landed to pick up the toiletries he needs. Some people think the dollar stores carry cheap products and junk, but that is not the case. The two biggest – Dollar Tree and 99 Cent Only – are very clever about what they put in their stores. Dollar stores now sell $20 billion a year and more are popping up. About two-thirds of the population shops there for every day items such as cleaning products, batteries and toiletries. In addition, dollar stores get treasure items from stores that have stopped selling them. An example might be a type of new cereal that didn’t sell that well in stores. So, instead of costing $4 or $5 in the grocery store, it’s just a buck at the dollar store. Clark has found cell phone cases and charges from his manufacturer for one dollar!
