Hi,
I am totally at a lost whether I could use "I remember to buy a birthday present for..." with 'remember' in the present simple tense.
Normally I would use "I remembered buying..." to say that I 'remembered' the time I did something in the past.
"I remembered to buy..." to say that I 'remembered' to do such a thing, but I havn't done it yet.
"I will remember to buy..." to say that some time in the future when Mr. A's birthday is coming up I'll remember to buy a gift for him.
So, is it legal to use "I (do)remember to buy a birthday present for Mr. A." when someone is nagging me about buying a present for Mr. A and I want to say that I do remember, I haven't bought it yet, but I plan to buy it this evening.
1) Is there another way to say it?
2) Is 'do' usable in this case?
3) Using the present simple with remember- a stative therefore have the same meaning as progressive?
If any of my uses here are incorrect, please correct me

Thank you very much.
