I remember playing a charity golf day and I was paired up with a chap who was sales manager for a local bakery company. Not fresh bakery but more those long life buns/cakes you see in petrol stations. I said to him 'yeah, I've bought your products before'. I asked him about a competitor product that sat alongside them and said they were always doing 50% extra free packs, or 2 for the price of 1 deals which made them better value.
He said two things to me. He said 1st thing, our product is better quality, but the second point was an interesting one. He said they do far too many promotions.
Expanding on that further, he said that the competitor has trained their customer base to expect promotions in such a way that it has now become impossible for them to sell the product without a promotion. He said that the frequency of the promotions has increased so much in the space of a year that the products became almost permanently on promotion. He also mentioned that he expected the business to go bust as a result. True enough, you don't see those cakes for sale anymore, the company has went bust. They accidently trained the customer base to only buy the product when it was on promotion, as the frequency of the promotions was simply too much.
Now I'm not saying the applies to Tesla but there is some learnings to be had from a story like this. If Tesla do more promotions at end of quarter, eg, cheaper deals from inventory or maybe free supercharger miles, or even both. Its amazing how quickly customers will respond to that. 2 quarters in a row of doing that would be the start of a pattern, and that would be a very unhealthy pattern to get into.
I'm not saying it would put Tesla out of business like the cake company, as Tesla has plenty of margin. But if you excuse the pun here, if you bake in a pattern of price cuts/promotions at end of quarter, then customers will respond to that new pattern very very quickly.
