Tiffany - I have not seen that specific plant set-up, but I have dealt with others like it that were filled with stones right to the bottom so that there was little space for water retention. That means watering it every day. Not for me!
I think you should try to pry off some of those stones and if you can sccessfully remove the top layer of stones there will be that much more room for water.
Lin - Indeed, it is all about generating sales, not about properly caring for plants. I see a lot of succlents, that are currently all the rage around here, potted in all manor of strange containers usually with no drain holes. Air Plants are another species that seem to lend themselves to strange containers.
