Does Dan ever have sales for GP? Like instead of 500 FB credits for 550 GP, he gives 10% off so it's 450 FB credits for 550 GP?

Or instead of a FB discount an increase in GP - like 500 FB credits for 600 GP (9% more)?

I think he should , Every Friday , Call it :
Friday Funday!

Dan would probably end up losing money as once the first of these events comes by, people will just wait for another rather than to buy something at full price.

It should not be predictable
If he announce it randomly - regardless of holidays - I'm sure that will boost up GP sales
and it should not be at regular interval, and not too close to each other GP discount, say about 4-6 months

ether way a lot more people will buy GP. Tho I don't think Dan would do something like this, could bring in some more money. I think I've even seen something like this posted before, spend 100 dollars get 10% off your next GP perches.

just btw, does not 500 FB credits for 550 GP shows 10% bonus? (500+50)

I like the idea of doubling or tripling your purchases, as long as it's capped. I've seen it in other games, and you wouldn't believe the amount of people that rush to the shop with the credit cards in hand.

Dan wouldn't actually lose money this way. He'd actually gain more.

^True^ Many people will buy it as there is a discount,many more than on regular days thus gaining a bigger profit on the special day.
