Like many companies there are very few items that are sourced in the UK. Most items come from Europe, China or the USA and are purchased in $ or €.
Unlike some companies that may adjust prices as soon as they know the product is going to cost more to purchase, we will only make adjustments when stock is replaced and starts to sell. So if a weather station is today £100, but tomorrow it's £110 thats purely because we've started to sell the more expensive stock.
We try to remain competitive and hope this explains to those that have emailed us.
