Would like to find something I can buy in a store, like the iTunes cards and the gift cards that most drug stores have on display.
PayPal doesn't seem to offer one, but you can paypal money to someone with an e-card.
Other companies, like Visa, MasterCard, Amex, and Discover offer physical gift cards.
Yes, PayPal offers a debit card, which can draw funds from your PayPal account. It can be used basically the same way a credit card is used.
western union has prepaid credit cards.you can use this to make online purchases.
