Now not only have they restricted the coupons but raising their prices on ebooks as well.
I went to get some HQ titles and noticed that Kobo has raise their prices on all titles.

Now instead of 20% off discount off the regular retail price it's 12%

This makes Kobo higher then Amazon, Books on Board and B&N on Harlequin titles.
So a HQ that use to be 3.89 is now 4.39
Amazon & B&N 3.99/ BOB is 3.86
I had to do a double take when I saw the price change.
I did get use this coupon but without a coupon now it just not worth shopping there like before.
