Beware of sites like Pro Design Tools.

Some sites try to scare people in thinking that software that you LEGALLY buy or receive from others isn't legal at all as this link suggests. However, in this case, calling Adobe themselves will prove the lies that these sites generate.


All you need is the serial number, Adobe can in fact verify if that number is valid or not before you even complete the transaction on these sites. Just 2 days ago a person was able to buy their software from E-bay and have it declared legal by Adobe themselves via a simple phone call.


Adobe does NOT sell previous versions of their software on their site and most of those people who do buy from E-bay and the like are doing just that, purchasing previous versions no longer available. Very few will buy current versions from auction sites, those versions are usually received other ways, or if they're honest, they'll get the trial and have it extended.


Buying student copies of the software doesn't allow you to use that software for profit, but you can still use your student discount on FULL versions. There is a difference between buying a full version with your discount and buying a student version. However, the discount isn't as big as some claim. You are actually paying MORE then even the upgrade price for that software. Where's the discount in that?  People prefer buying their software from places where they're sure of getting a cheaper price. 


I highly doubt Adobe is going to make it that difficult for people to buy legal software from other venues. 


The link is below, however, be aware that should you provide valid proof that purchases made from E-bay, etc. are still legally valid and do still allow you to register your software, they won't approve your comment.
