Hi Caleb, we put our envelopes through the printer. I have read some posts where they only leave the customer owing money for 1 clean, we have a 3 clean policy on anything under £15 and a 2 clean policy anything above of which we state to new customers, after all they want you, they contacted you and sometimes they just plain forget, we are only secondary thoughts to most but we give them a fair chance. It works for us but not for others, some of our clients have stated, they aprieciate us not calling for money especially during teatime. But we all do things differently.
