this is a great idea, but like a lot of people have mentioned, it might be a bit too steep in pricing, especially for the old ones. i donate regularly... but the knuffels i really want are 10

or higher... and i don't think i would actually donate $25+ more to aim for those (on top of what i'm already donating...).
i'm pretty sure the site's goal for this is to give incentive for normal contributors to donate more and people who don't usually donate to start donating a little. Considering the main targets would be older gen knuffels, so all the ones we want are high in price. As a normal contributor, I don't see why I would increase my spending to try to get that. At most, I will stop selling my :fc:s (or in my case giving it out for feeds), and save for the knuffels instead. For people who don't care for knuffels can just drive up the price of :fc:s cuz they can.
for people who can and don't used to donate, they might donate a little bit to get the monthly stuff (as the knuffels may be a bit out of reach) because they can't afford buying the :fc:s using

anymore. However, there may also be other people who used to donate a little, but now might quit. I'm sure there are people who can donate whatever they can, and then for the rest of the stuff they want, they may rely on :fc:s in the market... but if they can't afford the prices, then it's just demoralizing even tho they already support as much as they can.
for the rest of people who can't really donate for various reasons will basically just suffer in this situation.
this is just my reasoning behind why i'm not sure if the current pricing is a good strategy. i could be wrong.
i do understand that the older knuffels shouldn't be too cheap either because they are old... but 1

per level seems a bit too much. i think maybe 1

per 2 or 3 levels might work better for incentive for people to donate. it's not completely cheap, but a more realistic goal for people.
