The Bigstock website sells royalty-free stock photos and illustrations. In the past, you had to buy a pack of credits before you could download any of Bigstock's stock. If the purchase price of the image you wanted left you with an awkward amount of credits, that was just too bad.

Now you can buy a single image and avoid credit packs. Single-image pricing ranges from $2.99 (small photos) to $12.99 (extra large photos and vector images). However, buying credit packs does save you a little money, so if you plan to buy images regularly from Bigstock, you may want to go that route. Just remember that credits expire one year after you buy them.
