Is the reading drive still a thing? If so, when does it happen?

Most likely not going to be happening this year. Staff have wanted to try something new but there's been no info regarding that in a long while.
Someone correct me if I'm wrong, but I do believe Keith has said that there wouldn't be anymore Reading Drives...
last I saw, RD items were the next thing going to be added to the antique shop, they may have decided to change the order though. There's also not going to be a "reading" drive ever again, though we may have a toy drive or something similar.
No you're right, I believe he has said something of that sort.
Keith said there's never going to be another reading drive, not the way we knew it.
Thanks for the info guys, I realized that there's a lot of items in the shop that I want. Any way I can get them since there's a change there's no more reading drives? I've seen people "buy" reading drive points.

The items will come out in the antique shop in all likelihood. I saw Amber post that they would anyway.
There are two options for you.
One, go on the selling forums and see if anyone is selling RD points. This one is going to be harder since it's been a while, but people still have points here and there. Probably not enough for high end items though, like the 200 point items.
Two, wait for the RD prizes to be put into the Antique Shop for a set sP price. The Antique Shop is new, it takes old plot prizes and prices them so that newer users can buy them.
