iDrive does backups and related storage services. Commissions plus full reseller account where you pay for storage and then sell it. The commission one also offers 90% discount to the customer for the first year.
sfi4.com has a large range of products and an affiliate program.
Heatbit.com I got an affiliate account, 5% on all referred sales. But like many crowdfunded pre-purchase ventures it looked extremely scammy at first so I left it.
