Hi there,
Thanks for emailing support. Yes, you can upgrade in your account to the next license. If you go into My Account > Licenses. We run a number of sales and promotions throughout the year and you can find the latest and greatest offers listed on our Deals, Coupons & Discounts! page.
If nothing there fits exactly what you’re looking for, I’d suggest either subscribing to our email newsletter or following us on Twitter because we also make those announcements there.
Cheers!
Brendan
