Staples Ink Rewards, Historic Times for "Double Ink Rewards"?

[UkeDog]

Does anybody recall past months that Staples offered “Double Ink Rewards”?
I’m holding onto some (20) ink cartridges that I need to turn in this month.

From what I remember, in the past, Staples announced these towards the end of the month.
So now I typically wait near the end of each month before I bring my next batch of 20 into the store…

The last one I recall was the first week of April last year.
