You could break shopping out to yet-another device, but generally speaking you don't need to.
Services like paypal help you protect your credit card number. And also, even if you do get your credit card stolen, you can just dispute the charges and get the money back. If this happens a lot that's a problem of course, but the industry is built to tolerate this level of crime so long as it isn't excessive.
It helps if you do things like clear you cookies every time you close the browser, so session hijacking is a lot harder. But this is not very convenient. You could maybe do all your shopping on one browser that clears cookies and other web browsing on another.
No solution is perfect, it's all a matter of finding your right balance. But maximum vulnerability to hackers probably isn't it.
