I have a problem with those stores.
 

so i have buy some stuff from another players and sometimes it doesnt work. i go to players store and look what he/she are selling ang if i found somethin interesting, i press the right at mouse but still it doesnt buy it???
i have the money and i have look that it is not buying it, just selling. is it bug or what is wrong?

Were you on your mover? You can't buy while on a mover... and it could possibly be a slight lag in trying to buy as well.

ou jeah, i was on mover.. man i´m stupid XD
thank u very much :D

I've bought items on my hobby horse before. Usually you just need to close the shop/reopen it, or get closer
