500px, the worthy Flickr alternative for photographers, has a Black Friday sale. Coupon code: BFRIDAY
It’s $28 (after a 50% discount) by PayPal (recurring annually, note). That gets you a basic 500px membership, for which the main benefit is an unlimited number of uploads. There is a free account, which I was on previously, but it only allowed something like ‘four uploads a week’.
If you want to swop to 500px from Flickr then Bulkr Pro is your best option for bulk/automated download of the full-size pictures. I see they also have a discount currently, from $60 to $39. That’s a one-time purchase of a license key for the desktop Windows software. It appears that the license key delivery for Bulkr Pro isn’t automatic, and you may have to wait a while before the maker manually sends the email with the key.
