ORDER TSHIRTS FROM BANGKOK ON THAILAND ONLINE TEE-SHIRTS STORE OR FROM PLATINUM MALL AT PRATUNAM IN BANGKOK

Dear Personal Shopper team,

I am interested in using your service for a purchase of ~30 T-Shirts from the
Platinum Mall with shipping to Germany.
I already know the seller (we purchased from him during our time in BKK
before) and before placing the order I wanted to contact you to ask a few
questions:
– would the personal shopper fee also include a quality check? (the last time
we bought shirts some of them had minor mistakes (dark points, print not
clean))
– Since I want to order quite a high number of shirt the German customs will
probably want to see a receipt to calculate the tariff. Is it possible to get
a clear receipt in English and does the Thailand Post has a special form that
has to be filled to declare the customs value?
– do you know how long the delivery from Thailand to Germany will take
approximately?

Thank you in advance!
