IK Multimedia's 25th Anniversary Group Buy has reached the buy 1 get 9 free level. Depending on the number of purchases in the next 2 days, it could be extended for another month, which could see the number of free items go as far as 25 to 1 depending on the number of people that join.
You need to purchase before the group buy closes, but you'll have 30 days after the closing date to pick your freebies. There's a bunch of Frequently Asked Questions on the group buy page that are probably worth a quick read through.
I'm in at the $79 level currently, but I may make another purchase to double down on the number of freebies I'm eligible for, at another pricing tier.
The sweet spot seems to be to buy a $199 USD item because once you own one at that level you become eligible for crossgrades at that same price point, and you'll have access to 8 (or more) freebies at that same level.
Buying 200 Gear Credits on the website to spend in the Custom Shop (one of their apps that you can install for free) seems to be the cheapest way to get in at the $199 tier. There are various discounts that can be applied to get them cheaper than $199.
There's a lot of analysis at this thread with some great suggestions on how to get in at the cheapest price.
Also on that thread someone put together a Google Docs spreadsheet showing the various items available at different price points.
$200 for s/w… which ones should i get?
already subbed to pro tools. noob here though
