One person runs SniperCaddie: George Thirlaway. There is no support desk, so replies come when they come, but everything below gets read. More about the site and how it works.
Written in pieces and reassembled by the page. That stops the crudest address harvesters and nothing more sophisticated. If you have scripting off, the address is spelled out above.
What to expect a useful answer to
A price that looks wrong
The most useful thing anyone can send. Include the page and what you think is off. A median skewed by one mis-parsed listing is a bug we can fix at the source, and it is how several have been found already.
You are a retailer and want out
Say so and your shop comes off the source list. No negotiation and no conditions. Equally, if you would rather we read a product feed than your product pages, that is less load on your servers and better data on ours.
A data request
The privacy notice explains that the site holds no personal data: no accounts, no analytics, no advertising cookies. If you think that is wrong, this is where to say so, and it will be answered properly rather than pointed back at the policy.
Anything about the numbers
How a tier is decided, why a product shows no typical price, what a median is measured from. The data sources note covers most of it; the rest is worth asking.
What this is not: a shop. SniperCaddie sells nothing, holds no stock, and cannot help with an order, a return or a delivery. Those go to whoever you bought from. The seller's name is on every listing.
