So, don't have a credit card? No problem. Go to your local Gift-card selling stores. (They sell em anywhere, even at Rite Aid or Vons) Go to the Gift-card section and look for a PrePaid Visa Giftcard.
Normally, they'll have 2 kinds of them.
1. Loaded With Cash - Not Recommended (Most Common)
This means that they cost 25$, but come with 20$
2. Empty - Recommended (Un-Common)
These come with no money but cost 5$, you have to fill them up when you buy them. I recommend only putting 1-3$ on it.
When you get home, log-in to PayPal and verify it like a normal Credit Card. In 1-3 days they'll deposit a small-fee of cash into your account. Then tell them how much cash they put in, and you're good.
Normally to see you're account balance and activity there'll be a link on the back of the Gift card.
Once you've done all of the above, just pray to jesus PayPal doesn't make you do the extra verification process they make you do when they find something suspicious.
Also since it's a pre-paid gift card, you can use it to buy stuff from any store once you link it to your Paypal (If you have cash on your PayPal). Not only this, but you can now order stuff from Ebay ...
Anyways if you've done all the steps above you should be fine.
Congratulations, and Happy Spending!
