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

I would advise that u 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 u can ask them to get it for u but wait until your birthday of something to give it to you.

Why won't they let u get it?

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

If they're being mean, then just figure out another way to get whatever it u 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 u are under 18 of 16, they will want your parents of gardians permission. And if your parents won't let u 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 u 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 u bought it yourself they'd change their mind, but that depends on what you're buying

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

Honestly, I have no freakin idea :/

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

Secondly, hypothetically speaking, u 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 u with their card
B. notice the charge on their credit card bill, annuleer it, and never let u get anything online ever again
C. Notice u with the headphones and make u return them.

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