They are going to charge you tax up front,like last night I had 2 iPhone 15 pro max and the iPad 13 inch m4 or something and it was about 500 that it wanted me to pay,you can use a good fulls and it's not going to change how much it is,but if you use a bad one it can change ,but just put it to a addy where you can get to it to get your shit because it don't make you have it to what's on there is but what address you use use the same addy through the whole process,but it's a good come up the because you can literally go on a website and sell the brand new iPhone for about 600 bux even if it's tied to a carrier and sell the iPad for 1200 ,so with both phones and iPad that's 2400 bux that you made off of 500-600 bux,you gotta wait for them to ship u the phones then you ship them to that company so about a week and a half but get you a few started then you can have a good cycle going making a lot of money,the whole tax thing might be different in other states and by carrier ,I live in Texas and use it through att though
