I know almost none of us are fans of digital, but
DLsite is having a pretty great deal right now, especially if you're after IA and ONE AI at all. The coupon code gives you 30% off any product, but only lasts for 3 days after registering! I think they have more than CeVIO VBs, but CeVIO has the real savings right now.
All of IA and ONE's CeVIO AI VBs are also on sale for 10% off already, meaning witht this new users coupon, you can get them for 40% off.
I signed up just to see the sales myself, so here's the prices for them right now as it shows me:
IA AI Song/IA AI English Song/ONE AI Song - $59.52
IA AI Song Starter/IA AI English Starter/ONE AI Starter - $108.1
IA AI Talk/ONE AI Talk - $49.80
IA AI Talk Starter/ONE AI Talk Starter - $94.44
If you wanna get IA or ONE AI but didn't agree with the price, right now wold be the time.
