Why my 100 robux options not here anymore?

im trying to get 100 robux for a item on roblox please add it back to microsoft rewards thanks very much

i only saw 800 and 1000.

This is just stupid, instead of grinding for like a day to get 1500 points then redeem it for 100 robux. Now it's only 800 and 1000 robux and now I have to grind up to 7 - 10 days just to get 10000 points for 800 or 1000 robux. I used to get 1500 points, then redeem it for 100 now I have to grind 10 times the amount of time just for some robux when it used to be only 1500 points for 100 robux in a day which was insaney easy and efficient, now its just time wasting and point wasting. Sometimes you don't even want a huge amount of robux, sometimes you just want to do a few things in microsoft rewards to get to 1500 points and redeem the 100 robux for lets say a gamepass on a roblox game. Honestly a stupid move from Microsoft, just change back the optinions to the old ones that everybody liked and had no probem with.
