i work in sales, and currently there is a canon contest. the winner of the contest gets a 5dmkii ....... saweet! i know for sure im in one of the top 5 salesman of the company. but im in a low volume store, and of course its been slower than ever. im already giving up making all the money i can and strictly selling canon that doesnt pay me at all .... but my problem is i can get a canon 55-250is lens for $100 but if i buy it and win that 5d its useless! i just want to note that i have a 30d ...... what should i do? hold off and ride it out to see if i win or buy a decent lens at a great price?
