Thank you for offering me 10% off my first purchase after the order completes!!
What a joke of a company, cant cancel as no phone number, take 3 weeks to respond to email cancellation request then try to imply discount would not have been available, then change their mind and agree but WONT honor discount without sending back purchase at my cost then resend out at their cost, 5 weeks later and emailing back and forth told they would not refund the difference as against policy. Leaves a bitter taste in the mouth dealing with this kind of company.
