The Samsung Galaxy S7 unveiling is just around the corner and in-store ads are already popping up, promising early access for preorder customers.

Samsung will take the wraps off its latest and greatest flagships on Feb. 21 ahead of the Mobile World Congress 2016, where it will introduce its new Galaxy S7 and Galaxy S7 edge powerhouses.

Retailers and carriers are gearing up for the big launch and preparing their offers, and photos of an in-store point-of-sale (POS) display have now surfaced online, showing the first enticing offer.

As SamMobile reports, the image above is of a POS display spotted in a Three carrier store in the UK. Based on this ad, which was probably not supposed to hit the Web just yet, Three is teasing the "Next Big Thing" along with a promise that preorder customers will get the handset three days early.

The POS display is for both the Galaxy S7 and the Galaxy S7 edge, so the early-bird incentive applies to both new flagships.

If the rumored March 11 release date proves to be accurate, it means that customers who preorder the handset from Three should get their device on March 8. Preorders should go live on the same day as the unveiling, on Feb. 21.

SamMobile further notes that EE received the same banner to promote the Galaxy S7 and Galaxy S7 edge, according to its tipster. This indicates that the three-day early-bird offer will be available to EE preorders as well.

Another leak, meanwhile, consists of a brochure that reveals the specifications of the next Galaxy smartphone powerhouses. The brochure in question lists the Galaxy S7 and Galaxy S7 edge with 5.1- and 5.5-inch displays, respectively, both sporting a QHD resolution of 2,560 x 1,440 pixels.

The smartphones will further come with Qualcomm Snapdragon 820 processors, 4 GB of LPDDR4 RAM, microSD support, and similar designs to their predecessors. The Galaxy S7 should feature a 3,000 mAh battery, while the sleek Galaxy S7 edge will pack a more powerful 3,600 mAh unit. The handsets will also be waterproof, as Samsung recently confirmed in a promo video from its Indonesian branch.

It also seems that Samsung is taking a page out of Apple's playbook and equipping its new flagships with pressure-sensitive displays. The leaked brochure also confirmed the previously rumored March 11 release date, which should apply to both the United States and Europe.
