Donation, queue skipping

[Mashran]

I recently donated by buying 10 coins and bought an item for 5 coins. I wonder if I buy another item for 5 coins will the time that I skip queue be added on top of the time I already have or will it "reset" from the the second purchase and 30 days forward?

Maybe this have been asked before but I couldn't find it in the FAQ.
