This depends on the size of your parcel, your country, the weight, the items, the shipping service, how many working days are in the week and many other factors.
If I had to give you a rule of thumb to go by, this is what I'd say
- DHL: 1-2 weeks
- EMS: 3 weeks
- EUB: 3-4 weeks
You can use the shipping calculator to see the exact estimated shipping time published by the agent.
Whether you use Wegobuy, Superbuy, Pandabuy, Sugargoo, etc. doesn't really matter that much, their handling time is quite similar, and as soon as it's snet on it's way for international shipping it's out of their control anyways.
