I would call Samantha Rodnick at
1-800-253-2924 x 542 and she can answer all your questions. It looks like their standard onesies run from $4.00 to $4.45 if you order 5 dozen(600onesies). If you order less there is a 5% handling charge. All of their garments come in prepared for dye white and are not preshrunk. I hope this helps.
