I already told him about the price increase but he didn't seem to care. He would rather spend more money later and get it for me at a time that he wants, when he is not so tired stressed and more relaxed.
Thanks for all your opinions and advice. I talked to my dad about it and wasn't able to convince him to get it for me this weekend. He once again said he didn't care about the price increase. So now that I have to wait till my b-day in May, I am just going to make sure that I get everything that I want and even make him feel guilty if I have to.
