All you have to do is have very high INR rates on a consistent basis! Just ship everything on time, then sit back and relax while the post office does god knows what with all your orders! It's so easy, anyone could do it!
Wow. I've had many INR and always just refunded them right away even though it shows shipped on time, then it shows delivered like 6 weeks later. Do you respond the the INRs or just do nothing?
