Well, as we all are sure by now that current marketing department has no idea what to offer and at what price, thus limits forggy's profit (which is bad thing and not very healthy for game that is F2P) here is couple of suggestions to marketing people, who apparently are not gamers and have reputation of not knowing even real prices in game.
1. never sell stacked item for the same (or higher) price as single item. (1 for 70 or 5 for 350)
2. make sure you know what is current market value of product. When you sell item for higher price then original item, it just show us what we already knew/expected - sales department has no idea what they are doing.
3. offer discounts in higher range for higher sales. you're not selling tangible good, and having more items in game - more happy customers, more people play, in return will mean more progress and more future sale.
4. make selection wider, offer more of products and add some items as permanent items
5. throw gifts in large packs, give something useful. for example, not V rune or something low like that.
6. do scale discount. So if your pack regularly goes 10 for 20, offer 50 @ 15Dias, 100 at 10 and 1000 at 5.
It should be in froggy's interest to keep customers happy. We (customers) will spend more money if you offer us more for it, and that is just basic marketing strategy.
How does this works. If you offer for example AT charges at price I suggested on other thread (75% discount if you buy 1K), many of us will opt to buy more of them then we would otherwise buy. If more people tier their weapons more, most likely that will mean more people will run higher level instances (or be able to) and they will provide more items that will need tiering up.
So some products as AT charges, drills, jewels should be available more often, because they are more needed in game progress.
Anything I missed?
