That makes me giggle too. I had an Apple Visa card way back when. The maximum reward one could accumulate was something like $1500, IIRC.
This made me giggle just a bit.
I had about that much, a little less, when Montgomery Wards cleared out stock of the 520C for $499 each. I managed to find three of them, which I purchased. Then I redeemed my Apple Dollars from the card using that purchase. So the 520Cs were essentially free.
Then I sold the three 520C for about $1000 each. So in a quick week, I netted almost $3000...
Ah, the good old days...
