Shop Mobile App

Everytime I go on holiday and there is a sale, I miss it. For example this year's snowdown sale, I did not have money to buy RP to get the skins I had been able to get on sale, they were all really good, but then I did not have RP until I was on holiday in Christmas time. I was out of time and could not access my computer. This has been an issue for a while I think (at least to me) so I thought in the shower for a while and came up with an idea. Why not release a shop app for the game? Then people on holidays can still access the store. I think this should have already happened and it would be a shame if we did not have this. Tell me what you think.
