The 5% on gas and groceries has a rather low monthly limit of $250 for qualifying purchases though and its not straight cashback card. You have to have at least 2500 points to start redeeming. Do they come in set point buckets or can you use say 2650 points in a redemption? From what I can see without an account it looks like you are stuck to 2500 point buckets which would make this a really shitty card in situations where you aren't very carefully paying detailed attention to your spending habits and needs and when they don't fit into strictly defined little buckets
You can use them in any amount you want, just has to be a minimum of 2,500. So yes, you could redeem 3,413 if you wanted.
See bolded plus:
Its not a straight cash back - its a points system where you get 1 to 5 points per purchase which you can then apply assuming you've met certain point accumulation totals within the billing period. If you used it just for gas or groceries you'd need to spend $1500 on gas in a month to qualify for the credit which would get you 1.6% Cash back on gas
If you max out the areas its a bit easier but it looks like if you don't hit 2500 point increments you lose out on cash back opportunities
