(Kinda) pay what you want for 10 Mac apps. (I tried $0, they tell you "Your payment amount must be between $8 and $10,000!") Whole list:
- iRip ($25 USD)
- Lucid ($45 USD)
- Crossover ($40 USD)
- DiskDrill Pro ($89 USD)
- HDR Darkroom 3 ($89.99 USD)
- Vitamin-R ($25 USD)
- SyncMate Expert ($40 USD)
- ForeverSave 2 ($20 USD)
- Back in Focus ($99 USD)
- Beautune ($30 USD)
Haven't heard of any of them before except Crossover, but some of the others look like they could be useful too.
Then I guess it's not pay what you want then.
