There are only some products/ranges that are stocked on-site by CHC, as funds would not allow all of the items to be stocked on site. So, many of the products are 'drop-shipped' - delivered direct from those suppliers who have offered CHC this option. We are obviously limited to those companies who provide us with that service for the standard of products we wish to make available (ie. we wouldn't use companies that provided that service and were cheaper but didn't offer the quality of product that we know is better for your pet).
