Thats how I do about 90% of my business.
For the "doubters" , I offer them a chance to come to my house and pick up tickets. Some people come from as far as Kitchener. Once they see I can be trusted, they order tickets by Credit Card (or EMT) and I send them PDFs from my account. Easy peasy.
Are there people sending the same PDFs to different people? YES!! Thats how I have built my business. By trust.
And the preseasons this year were not printed as tickets. They are only PDFs from our accounts.
The process is legit. Make sure the person you are dealing with is.
