Calumet initially refused to deliver to our offices "because out order was too large" . Following the order being placed were were contacted by email asking for additional information to verify the puchase given its value - that's fine as our business occasionally acts in a similar way. Then despite being given this information promptly Calumet then flip flopped between agreeing to ship and demanding we attended one of their stores. They did not return email quickly or return calls within agreed timelines. Eventually they delivered a day late. The kit itself is good and the site easy to use. I would recommend them as a company but for big purchases you're better off visiting the store.
