today I just thought : What has never been discounted before ? Why do I get the feeling that I have seen everything already ?
For example : Collectible bags. I only remember them being discounted once or twice since I began playing (and that was last October).
Or Hair Dyes. Rarely be discounted. Same goes with Armor Kits.
I think that with a little bit of marketing research it would be relatively easy to find this out : Check all the DDO sales from last year until now, and just compare this list with what's available at the DDO store.
That just as an suggestion.
I had this idea partly because I would like to buy really big collectible bags - but they are too expensive for my taste, personally. The biggest ones even cost as much as adventures do, and if I have the choice, then I *always* prioritise Adventure Packs higher than everything else. Personally.
