所以assume all purchase comfrey cream price will be 15.1x0.89=13.4
theTreeHouse sell £16.72 GBP include international shipping (diff £3.3 for shipping fee)
taking (45x1.07) £48.15 as shipping fee, at least we need to have (48.15/3.3)~15 order to beat theTreeHouse
If my above calculation is correct, as long as we can accumulate to 15 items, we can order already.
Am I correct?
