Prioritize 4Ps for Online Companies
Arul Vijay, Student (MBA), India
I will prioritize as
1) Place
2) Product
3) Price
4) Promotion.

P's for Online Auction Company
Olajide Alfred, Business Consultant, Nigeria
I would want to put product ("the what") naturally first in the case of purchases from a physical location, but in this case, the main value proposition is that of "an easier and alternative location to purchase what you would normally buy in a physical location".
In this regard, we may want to say that the product is "actually the service of providing an alternative channel", with the place being the "web and webpages".
As such the list still remains the traditional product, place, price and promotion, its just the twist to the definition of the product. Any thought on this?

P's for On-line Company
Michele Hinds, Business Consultant, Barbados
First you must determine what is a buyers decision for using the on-line service. Once you have determined that, the prioritization will follow.
You need to study the buyer, in terms of the P's (expand on the P's as much as possible, not so easy to group in those four) and then put the reasons for buying into the groups, and put merit to what you consider the most important to the least important.
