I like how easy it is to use, as well as customize each post card for your business! It's affordable too if you have many customers or clients in one area/state that might be interested in what you're offering them (which my restaurant does). The most useful part of this product has been getting new leads from potential clientele who were not aware we had anything specific they should consider when looking at their next meal. This also got our logo out there more than any other marketing material could do alone.
