The best August 8, 2018
Reviewer: Eric Cecil from Vancouver, WA United States  
I purchased a BCG from sharps and just want to say what a wonderful experience I had.  I originally called to ask a couple questions, but happened to be after hours.  I did not leave a message and just ordered online anyway.  The next day the called me to make sure everything was ok!  What service! Free shipping was offered with my purchase, I want in a hurry so that's what I chose.  Imagine my surprise when it showed up in 2 days!  That's right, free shipping wasn't the usual bottom of the barrel shipping at 7 ton10 days, they sent it 2 day USPS!  Excellent company and great product!
