Because people selling the item want more Robux.
There is no hack for Roblox! And, no. I'm not sorry. It is bad to hack, in fact, it is illegal.
Get a lot of tix and then convert your tix to robux or you can buy robux.
buy membership, daily login, or get a lot of game visits
You either buy the robux, get donated or get a lot of place visits and use trade summary to trade tixs into robux.
You can either get a lot of ROBUX or as I have heard, buy BC. The more Game cards you buy the more robux you get or longer BC
To get a massive amount of ROBUX you need to trade A LOT of Tickets into Robux or buy LOADS of Robux, preferably 15,000 (15k) Robux.
You do not need them, if you want to have a lot of tix and robux, earn it but if you wanna hack I suggest you not try, you will have a end result of you being banned from ROBLOX.
Try asking multiple friends and usernames for Robux they can donate Robux to you.
They cost a lot of robux. Go to gear and the have cupcake cannons, pistols, paintball guns and more.
make a shirt and call it DONATE HERE!!!sell it for robux ,if it looks good enough or you have a lot of ppl you know will donate,you should end up with a stack of dough

Either get some form of builder's club and wait, or get the equivalent of 1000 Robux in tix by getting 1000 place visits, then exchange them.
