Is there a limit on how many you can purchase?

Can you use the UP Rewards on the item you are purchasing? Or is it just on a future item?  Let’s say I buy 2 nail polishes, will the dollar be taken off during the transaction? Or is it for another item in the store. Thanks!

***i scored another deal also at Rite-aid***  Rite aid has the Loreal True Match Roller make up reg $13 or $15 75% OFF witch makes it $3.73 & they also have the Loreal Hip shocking shadow pigments on sale 75% OFF. reg $12.99 witch makes them only $3!!! Plus to score even better we have Loreal Coupons for the eye shadow -$1.00 that expire on 8/1/12. So that makes them $2 each!! ……..i went to 2 different Rite-Aids. One had the sale advertised with signs the other did not so i had the cashier price check them and they rang up 75% off!! so go check yours this is a great DEAL!!!

i found a 50 cents off one nail polish on one of the nyc displays……so keep an eye out.
