Then it can remain part of the regular sale, not as a daily deal.
Going from the regular Xmas sale price of 25% off to the daily deal extra markdown of an additional 8% to 33% isn't much of an extra deal? Is a daily deal that only saves a few extra dollars worthy of a daily deal?
I don't consider a $50 game 40% off at $30 stupidly cheap, nor would I find it 60% off at $20 stupidly cheap, but that 60%/$20 would make my rule.
(Still wouldn't have bought it @ $20 anyway though...)
Agree'd I stick to one Rule $5 - $10 Max
