What to get my bro?

its my brothers 16th birthday in 5 days, he will be 16, my other brother just turned 18 and i have a sister who is 13. THey all live 300 miles away ad we only met 5 years ago, im the oldest, every year i buy them birthday and christmas presents and i have never recieved a card back not one, its my birthday on tuesday and my brothers on friday, i was thinking of downsizing there presents from now on because im sick of not getting thanked. if they were younger it would be different but at 18 and 16 they should be able to ring and thank or send a card, im not asking to much am i???? any ways i was going to send a cheque for �16 what do you think???
