You think 5$ for one week wait time is too much or is too low? Iam of the opinion it is okay.
Maybe you do, but I can't imagine there's going to be a lot of sales of them. Not when all you're doing is saving someone a week's wait for a pretty finite function. It's not like it's a multiple use item or anything, and when the average player will just put the pet in storage and haul it out a week later to bond with it, it makes the item seem pretty overpriced. Consider that at least with the garden beds, you're saving someone having to perform some specific task.
And again, the price points should encourage the purchase, otherwise, why bother put the item up for sale in the first place. As for balance, I get that the garden beds remove the need to perform gardening, excepting that you have to wait the full time for them to reach maturity anyway. Which is to say while you're pulling out the having to water, potion, et cetera (which might have some economic impact in-game -- if there was a real economy to impact), but you still have to wait the growth time, so its balance impact is limiting. Essentially, they've priced the garden bed at "buy 2, get 1 free, but you don't get any of the other stuff you used to get when you were buying the original 2 in the first place." It's a poor value based on the set it came from.
All in all, these price points are too high for what they are. Not saying they should be free, but reasonable. I think $2.99 for small things is good (ie: the pet bonding potion), and the beds should have had a maximum price point of $4.99 each -- $3.99, however, is where I'd set it as optimal.
And yeah, I suspect we'd have to all become shareholders to see the sales of these because they'll never, ever tell us, but mark my words, the sales on these will be poor. (Queue people rushing in to tell me they've bought them, thus indicating that "everyone" will buy them. *grin*)
