I think raising the battery price might price Bloog out of the market. It won't be long before someone is providing a product that is similar in performance. When that happens the new provider will more than likely either have an "enhanced" product and will charge the same or slightly more for it OR they will have a product that is the "same" and charge less in order to garner market share. If, when that happens, Bloog is perceived as being overpriced (and potentially sub-standard stocking and CS) they will have positioned themselves negatively and will lose customers and new business more readily.
In this instance, regarding the kit pricing, it is actually more of a Customer Service issue. It creates the negative perception that the company is attempting to deceive the customer because there is an expectation that a Kit would be cheaper than the sum of its parts. At Bloog only ONE kit, the Ultimate Starter Kit, is cheaper than its components.
For e-commerce, where most shoppers buy on price, and where the PV community is always looking for the latest and greatest and the tech is so damn fluid and growing, it is imperative that pricing be carefully considered and not solely based on some internally desirable price point.
