A leaked Sprint holiday ad has outed an upcoming deal that some of you may want to take advantage of. Starting this Friday, December 7, and running through December 24, Sprint will be offering BOGO (Buy One Get One) deals on select Samsung Galaxy smartphones.

Phones currently listed as part of the promotion include:

• Samsung Galaxy S III
• Samsung Galaxy S II
• Samsung Victory

As expected, the Galaxy Note II appears excluded from the deal. Still, being able to grab two Galaxy S III devices for under $200 is as good as it’s going to get on Sprint. Sure, you could hit up Amazon Wireless and get two Galaxy S III devices for $100, but that’s only good for new customers.

If you’re a new customer, I suggest heading over to Amazon Wireless, if you’re simply looking to upgrade, you’ll want to stop by your local Sprint store sometime between December 7-24.

I still view the Galaxy S III as one of the top Android devices currently available and completely worth the buy. Sprint on the other hand, that’s your call.
