I am glad you asked. I have one that I am trying to get rid of. The exact one in the picture with the rainforest thingy. Come collect in Victory Heights.
I wish you'd asked a few months ago - our Jumperoo has been sitting gathering dust for over a year and we've just dug it out for DD! There are always a few on Dubizzle, though, and I'm pretty sure you'd find it easy to resell once you're done with it.
i have a feeling i wont get much use out of it, not more than a couple of months. if anyone has one in storage that they wouldn't mind temporarily loaning out, i'd appreciate it!
