Pretty much any site with -us is no good. Buyer beware.
I bought my Airbug from MidwayUSA for $120. Fast shipping.They've been in business forever and are very well respected.
Some of these scam sites look better than many legit sites, at lest price and availability wise LOL
I almost got suckered by them once, but my CC Company blocked the charge due to the site being suspicious! Fortunate for me! But you are right, the site looks legit, the address is even a legit place, just has no affilation with the scam site. And, be forewarned, they have more than one website out there! They look similar but have different web addresses.
