I find that in general, the Advent calendar has something for everyone- remember that even though you guys might not like the prizes every day (or even most of the days), throughout neopia there's lots of users who collect whatever is given out. For example today's prizes would be great for people who collect eyewear or sunglasses, bruce-related items, guns or snow-related items. Don't worry, there'll be plenty of prizes that you both like I'm sure.
I personally don't like getting books in the advent calendar. I don't read them to my pets or sell them, they just sit in my sdb because I won't use up single-use prizes. I prefer plushes/toys and wearables.
Yes, you are absolutely right! And I did think about it in that context. My only issue was that the items are "gift" items and therefore non-usable for anyone other than the people who collect them. So, like during the GMC one of the prizes was a toy pirate boat. I am sure most people found it useless. I happen to collect pirate items, so I found it absolutely GREAT! But all of my pets got to play with it before it went into my gallery. (If they happened to break it, it would have been MORE valuable. lol) But my point is, even to people who don't collect pirate items, it was still usable to them for their pets to play with. That was my ONLY complaint.
