Juice Box question. Buy disposables for more $ or reuse and save my $?!

I am starting to think about if I can save $ by reusing juice boxes rather than purchasing them for the next 16 years I am raising my kids LOL. What do you think?!?!

On average a box of juice boxes is around $2.50 (before sales and coupons of course.) Of course if I can find a deal I will stockpile them. There are single Rubbermaid 3117RDSPA Litterless Juice Boxes that I could wash and reuse (also sold by the case)  Rubbermaid Litterless Juice Box Blue, Case of 12 which might not only help the environment but save me money down the road.

I could also save $ using juice concentrate instead of juice boxes (article on that is HERE) which could trim down my juice spending by 75%! Something to think about.

Thanks Camille!
