New reports suggest that selected Best Buy stores will sell the $100 HP TouchPad tablet starting on Sunday.

According to a store manager in Los Angeles, the TouchPad will go on sale when Best Buy opens its doors on Sunday at 10 a.m. The new sale will apply to all Best Buy stores that have stock as some stores are out of stock at the moment.

The retailer added that stores typically have stock in the tens of units, and not in hundreds. He was, however, confident that if customers started lining up, the stocks could diminish drastically.

Both the models of the TouchPad, 16GB and 32GB for $100 and $150 respectively will be sold, CNET reported.

Previously, Best Buy in Canada started selling the 16 GB TouchPad for $99.99, compared to its previous price of $399.99. The 32 GB version of the device also had its price cut from $499.99 to $149.99. The site said that the sale ends on Aug. 22.

The fall in prices came just a day after HP announced that the company will halt the device’s production and will shut down operations for its webOS devices.

The company also, reportedly, sent a memo to its associates and announced the $300 price cut, which will came on top of a $100 price cut that went into effect earlier this month.

HP will be lowering the price of the TouchPad beginning Saturday 8/20/11. This is the lowest price ever for the TouchPad so please post it as soon as it goes live, the memo read.

The 9.7-inch HP TouchPad comes with a 1024x768px resolution and has a 1.3 MP camera with video calling. The tablet is powered by a dual core APQ8060 1.2 GHz CPU from Qualcomm Snapdragon.
