Dave:
If I pay them wholesale, I pay about$2.50 a pound. On Canal St they are currently around $5 a pound but that will come down to around $3.50 a pound in a week or two.
Of course, all bets are off as to what you would get charged in Aruba.
My fave lychee is mauritius. it is also the fave of everyone I give samples too. but brewster is very good to. personally, the only lychee that i can't eat in bulk, is hak ip.
i would ask them to supply you with 75% mauritius and 25% brewster
