Quoted from SKWilson:Not wanting to carry that much cash, I have purchased one pin with cash, one pin with a cashier's check and two via PayPal. Pretty much the same as 'cash on the glass'. Just ask the seller what they prefer. If using PP only do it in person after you've inspected the machine and agree on the price.
You wouldn't be buying from me then... cash and carry. Paypal is NOT the same as cash as you can contest the payment. Since there is no evidence of delivery the seller is screwed. Checks can and HAVE BEEN counterfeited.
