I ordered my Auto Vent Shade bug deflector 18174 on Thursday afternoon, June 14, 2012, and had it on my front porch by Tuesday, June 19, 2012. I thought that was fast shipping, especially considering there was a weekend involved. The price was also very reasonable. I am anxious to install my new bug deflector. I will be turning to Autoplicity in the future for my auto needs. Great Job Autoplicity!
