First come, First served

QUESTION

We would like to run a promotion where the first 300 of sales of 2 specific products gets $200 off, then automatically changes to $100 off for the next 400 sales (so sale 301-700), then switches to $50 off for the next 500 sales (701-1200).

Could we do this by checking how many times the discount code was used?

ANSWER

YES. You can run promotions where the first X sales gets Y% off, then automatically changes to Z% off for the next X sales, etc.
