Do you really want a Playstation 3 but your parents will not budge? You will need to try these steps:
1.Find out about something your mom or your dad wishes you would do. For example, if your dad really wants you to play more sports, ask him if you can have the PS3 if you play more sports for an agreed period of time.
2.Make sure your parent say they will buy you the PS3, not just say that they'll consider it, because that is not for sure that they will get it. Do not press them too hard or they will toss your chance out the window.
3.Try not to get your parents angry by reminding them to get you it too frequently. Every other time you drive by a game store might be good. Might. If they seem to be getting annoyed you should back off for a while.
4.Try offering to pay for some of the console, maybe $100 making it less expensive for them.
5.Ask for extra chores around the house. Start helping out more. Show them you can be responsible and are deserving of the PS3.
6.Also you could throw in there that all dvd's are being updated to blue ray and a blu ray player is $700, but a PS3 plays blue ray and is simply $299.
7.Give them a reason to buy it. Dont have Straight F's in class and do more chores so they know, you can act mature if you get one. And if you do this, ask around christmas time (or Hannukah or Kwanzaa) or on one of your Birthdays. Maybe even tell your parents that all your freinds have it and your left out maybe, show them all the stuff you can do on it make it sound positive, like you can do your homework on the internet on the ps3 etc.
8.Look for a website or store with cheap a PS3 on sale.
Act like an adult, not a whiny child. Your bargaining position will be much stronger. Find a key point to rally around such as good grades or extra work done in the yard all summer.
Remember this is extremely expensive. Perhaps your family can't afford it. Be reasonable.
Stay calm and don't get too worked up if they don't want to buy you the console. Instead, take a step back and wait until finances or other situations may improve.
Don't give a long list of items you want for Christmas or your birthday and add an expensive PS3 on top of that. Scale your list down to just the PS3 and a game or two. You can't have it all so figure out if the PS3 replaces the other items on the list.
The best times to ask is when you graduate from 8th grade or your senior year in high school. Your grades need to be good though.
Try playing up the fact that it can play Blu-ray and stream video over your home's network. It will be a device the whole family can enjoy.
Don't brag to other people: they will blackmail you.
Tell your parents they can lower your allowance if they buy it for you.
Don't give up, it took me over four years to get a PS3, but it's better than nothing.
Don't black mail, it never works, and after you try neither of you will get what you want.
