Personally, I only ever buy DDO points when they are on double bonus points. In the distant past I bought DDO points and the next day they had a double bonus point sale, it was a real slap to the face. Especially since there is no such thing as a sale on DDO points. There's no warehouse where DDO points are piling up and they need to have a sale to clear inventory. They don't have to sell off the remaining stock of this year's DDO points to make room for the next model year. It's an entirely virtual product, therefore rather than double bonus points being a sale, buying DDO points when they aren't having a double bonus point sale is in reality a penalty.
The thing is, I imagine when they look over their revenue at the end of the year they think, "Those double bonus point sales really work! Look at how many more DDO points we sell during double bonus point sales compared to when they aren't on sale." Except I'm sure there are a great many players like myself that solely purchase points during sales, not because they are tricking us into buying them at that time, but because we don't buy them at any other time as we do not want to incur the penalty.
This is especially true with bigger point purchases! The more points you buy when they are not on sale, the bigger the penalty you are assessed.
Even with just the $60 point purchase you are giving up 2550 DDO points when buying it outside of a double bonus point sale. That's more than Mists of Ravenloft costs in the store!! With the $100 point purchase you're being penalized nearly 5000 DDO points for buying outside of a sale! That's a +8 supreme tome! Of course they are going to sell more when they have a sale, who wants to be penalized thousands of DDO points for buying outside of a sale?
I bought enough points on the last sale to buy Ravenloft and a few odds and ends. I actually rather like Ravenloft, except I had no idea how much inventory space those filigrees were going to eat up! That's with just one run through... and I only got one of the ones I want. I can imagine by the time I get the 5 I want I'll have hundreds of the rest. I was playing on a first life toon that I used to run old school epics with, and he doesn't even have the 2 extra inventory slots, so I load up the store to see how much a filigree bag is, which doesn't appear to even exist, and a couple more inv slots... well, I just don't have enough points. Since there was just a double bonus point sale, I know it'll be a minute before there will be another. Now I'm stuck waiting months (if I'm even around by then), which sucks for me, and they aren't getting my money, which sucks for them.
Do you buy points outside of a sale? Would you buy more if they were always on "sale"?
