Just received your shipment today which accounts for only 10 days delivery time. An excellent result; hopefully the treatment will be equally successful and you will have found yourself a reordering customer.  

We placed and order earlier in the year and your company was great. Just wanted to let you know, that we placed another order recently and as positive feedback is not often forthcoming, we would just like to say what a fantastic job your company provides. Keep up the good work.
