Got my strings today, shipped Tuesday from North Carolina. The StringThis customer service number is shared with Strings and Beyond, also in NC. My Paypal receipt wasn't showing the 20% discount. I called and left my number and they emailed me and did a follow up call. Their system has a problem with discounts through Paypal. I got the discount and my total was $48 for a set of Chromes and 2 sets of Rock Masters delivered.
