comments: Your customer service is excellent - responsive and goes the extra mile. Worked with Rachel, who was terrific. The website lagged a lot, but may be new year's eve traffic. Also, a coupon supposed to expire on 1/1/22 did not work when ordered on 12/31/21. Overall however, your service and availability of labs, which is most important, is excellent.
