Well, I think they are gaining in popularity... The closest store that I might be able to set a few up in is at least 30 minutes away so I don't get there too often. Last time I did I pointed out that the coconut shells she was using for her rodents were ones that I made and were stolen from me(long story)... I wasn't asking for them back or anything... She said she liked them so I told her that they work in fish tanks as well... I think I'll make up a couple for her and bring them over next time I go there. The only downside to it is the amount of money I would actually make off of them. Those pet stores like to triple the price of everything so I'd have to sell them to her cheap... It might be worth it though. I'm still waiting to see if she's going to open up another store, If she does it will be less than ten minutes away. That would be really cool... Have you seen all the ones I have in my gallery? To answer your question we buy our coconuts at the local grocery stores. They are cheaper in Massachusetts where the rest of my family lives but that doesn't really help me any... and sales tax is not 8% here... what can you do?
