Hi,
Just discovered this myself. This item (pictured with '98' on the front) is the HIGH capacity cartridges - thus the higher price. This is new - when I bought my Epson Artisan 800 a few months ago, they didn't have the 5/pack in a high capacity.
The other one (with '99' on the front) is the standard capacity. If you zoom up the images, you'll see it notated under the 99/98 on the package front.
