While Amazon doesn’t often discount its Kindle devices, the company is running a promotion on Kindle Fire for Father’s Day, offering shoppers a $20 off coupon.

Today through June 8th, the Kindle Fire HDKindle Fire HD 8.9″, and the Kindle Fire HD 8.9″ 4G are all good for the discount when you use the promotional code DADSFIRE at checkout.  The offer is good while supplies last. The promotion is only good on one device per customer, and it’s only good in the U.S.

Barnes & Noble has run Father’s Day deals on its Nook devices in the past, but so far the company hasn’t mentioned such a deal on their site.
