Downloadbuyer

Downloadbuyer.com has a large selection of software available, such as Paragon System Backup, available for download today.
Downloadbuyer sells a fairly large catalogue of when known and established software titles.
In downloadable format only - no physical boxes.
Once you place an order they send an email to you.
If you order that now it would (should!) be with you in around five minutes and you should be using it in 15 minutes.
(And they are very well priced too!)
And they are officially licensed by every developer to do so.
If you want to wipe potentially sensitive information then I can confirm Paragon is about as good as it gets.
Paragon is one of the oldest developers of Hard Drive software.
Most have to copy them - in other words they generally lead the market.
