TLDR: For the love of cycling.
Why we do it is certainly not a million-dollar question, because the margins in this industry are tiny. Cycling is my hobby and I encounter the same questions frequently. Hence, I started Bicycle Couriers during Covid-19 lock-down (also because I was a bit bored). This is the online version of a very successful previous venture along the same lines.
Getting back to the tiny margins. A single mispriced delivery would set us back quite a bit and that is why it is important to have our systems in place. Hence, we reserve the right to adjust prices after payment and before shipment to cater for the unknown and unforeseen that might cause the transaction not to be financially viable anymore. Alternatively, we could refund the net amount after costs to you and cancel the transaction. However, obviously we don’t want to do this, and we have never done this before, touch wood.
