so let be clarify - I can use my Chase Sapphire Reserve to get 5X points even on Gift Cards bought at the Grocery store? Do the gift cards have to be of a certain type - i.e. gift cards for that store itself? I am guessing no since the only information that shows up on the bill is that it is under the category of "Grocery stores".

Now, for the question I would also want to know - I have about 50,000 UR points, if I buy $1500 worth of gift cards at my Grocery store, I get 7500 worth of points and I can erase $112.5 worth of purchases so that represents a cashback of 7.5%? And the 7500 worth of points isn't clawed back when I use them to erase the original purchase correct?

In addition I also have a Chase Freedom that has a 5X groceries categories that has been active for Q2 (April, May, June). Is the $1500 limit across all Ultimate Rewards cards per user or is it individual per card?
