Last night I was looking into purchasing the Plugable USB to RS-232 DB9 Serial Adapter on Amazon and was in the process of researching and this morning when go back to Amazon the price has increased. Is this normal that if you see certain interest in the product, the price is raised? Even though it is not by much but it is the principle of it.
Thanks for asking. This is a good chance to explain how we handle supply and pricing.
An important part of what we try to do at Plugable is run a lean supply chain. That lets us price aggressively (because we have less inventory risk) and have the most up-to-date possible product (in each batch, we can make documentation and product improvements) – but for better or worse, it also means things are dynamic in terms of supply and pricing.
We frequently adjust our discounted pricing to account for demand and other special events. In the case of this serial adapter (“list price” is 19.99), we were out of stock two weeks ago, and project that we’ll be out of stock again in March. Because we’ve been struggling to keep the product in stock, yesterday we moved the Amazon price from $10.95 to $11.95. It’s likely to remain at 11.95 for some time.
Sorry about the dollar difference since your research yesterday - we understand that can be frustrating. It causes you to have to think again about whether the product is still the best value. But we don’t make these moves capriciously - there are factors driving the change.
Thanks again for asking – your question helps others understand any pricing changes they might see day to day.
