Even larger retailers purchased some celery from wholesale firms, usually those on terminal markets. Proportions ranged from small amounts or "fill-ins" to as much as 85 percent bought from wholesalers by one retail firm. Retailers that normally buy full loads directly from shippers obtain partial loads from wholesalers or from shippers with capabilities of providing mixed loads. As expected, retailers handling smaller volumes of celery bought most of their supplies from wholesalers or repackers. Over half of the celery volume handled by firms classed as "small" came from whole- salers compared with six percent bought by "large" retailers (Table 7). One exception to the general findings noted just above is in cel- ery heart volume in the Boston area. Hearts make up a higher propor- tion of retail celery sales in Boston than in the other two market areas, as discussed later. Several repacker-wholesalers in the Boston area provide most of the celery hearts for retailers there.
