No lo mandan todo junto:
Sorry for delaying response.
With the rapidly development of our site, we have retailed some more warehouses, so the items of different orders may not be received by the same warehouse, we are regretful that we cannot promise you to pack and send them together.
Actually your parcel will be easier cleared by the customs if it is not complicated and heavy.
Moreover, even if we pack and send them together, the shipping cost will not be saved.
Sorry again for any inconvenience and hope for your kindly understanding on the matter.
