I have used Harilo's service quite a bit. This works for people who want niche products found only in U.S. and cost is generally not a problem. But, they didn't have a grouping feature as you said. (However, if you buy 3 quantities of something from amazon or other site and it is already sent as a single parcel to harilo's US warehouse, then it is a single package). Grouping the package is how they save money in shipping, and exactly where they make most money, so I am not surprised.

Regarding ujl's comment, it is typical of our 'गफाडी' mentality. We know little, we assume a lot, provide our own pet theories and talk a lot.
