"I wasn't sure about ordering without paying upfront, but the process was exactly as described. Someone from Kalvena rang me the same day to confirm the address, and the pack arrived two days later, neatly boxed. I paid the courier by card on the doorstep and that was it — no fuss at all."
Ordering was straightforward and the phone call to confirm came the same afternoon. Delivery arrived well packaged within two days.
