The global tablet shipment for the third quarter of 2015 declined by 12.6 percent, continuing a four-quarter trend, according to IDC. It makes sense, therefore, for Android tablet manufacturers to pump more deals on Black Friday to prop sales in the last quarter of the year. Consumers on the lookout for new tablets from today until Thanksgiving will not be disappointed.

Topping the list of killer tablet deals is the 10-inch Dell Venue 10 5000 Series tablet. Dell will slash $290 off the $517 price of this mobile device as part of the pre-Black Friday sale. This is offered at Dell Home through its Member Purchase Program. The company is also going to sweeten the deal with a free keyboard and free shipping.

Groupon is also offering 35 percent off the Google Nexus 7. It is now available for $125 from $199 and will be on sale until stocks last. It will also ship free with an optional cover. More than 1,000 have already snapped up the deal as of this writing, so head to their website before the deal runs out.

There are many Samsung Galaxy tablet deals across retail stores, but the best we spotted so far include Kmart's Galaxy Tab 4, which will be sold for $120, saving consumers $60. The pricing is the same at Sears, but Kmart is offering consumers $20 in points for Kmart Shop Your Way members.

Samsung's latest Tab S2 9.7 will also be available at both Best Buy and Staples for $340, 20 percent less than its original retail price. The incredibly cheap Amazon Kindle Fire (2015), priced at a measly $50, will still get additional $15 discount.
