How do I buy something off the internet without my parents?

I would advise that آپ don't do that.
Respect your parents.

I simply wouldn't. They'd probably get mad if they found out. Save yourself the trouble and just ask them; if anything آپ can ask them to get it for آپ but wait until your birthday یا something to give it to you.

Why won't they let آپ get it?

If it's something they legitimately don't think آپ should have, then آپ should respect that.

If they're being mean, then just figure out another way to get whatever it آپ want so badly.

Even if it were in secret, your parents are bound to find out somehow. They always do. They will know you're hiding something. Most online stores, want the costomers to have credit, and if آپ are under 18 یا 16, they will want your parents یا gardians permission. And if your parents won't let آپ get it, may not sound fair but it could be for a good reason. I don't know what else to tell you.

Sorry but آپ should really obey your parents on it. What I normally do if I want something online though is offer to buy it myself. I got fifty shades of grey, darker, and freed that way. I just paid my parents how much I was going to pay on their card. I had permission every time I do this. Maybe if آپ bought it yourself they'd change their mind, but that depends on what you're buying

Maybe get a friend to buy it for آپ and آپ pay them back?

Honestly, I have no freakin idea :/

Well first off, if it's Beats earbuds آپ want, and آپ have your own money; can't آپ just go to the store and buy them? It's a really مقبول brand every electronics store sells them.

Secondly, hypothetically speaking, آپ could steal their credit card and try to enter the information yourself. However your chances of getting caught are about 110% because your parents will either
A. catch آپ with their card
B. notice the charge on their credit card bill, منسوخ it, and never let آپ get anything online ever again
C. Notice آپ with the headphones and make آپ return them.

Long story short, look for them in stores and buy them with your own money if آپ have it, otherwise just wait, maybe آپ can try getting them as an early Birthday present یا something?
