I would like to ask how much was the service charge for each exchange trade?
You can see the details about the fees on their FAQ.
FEES AND CONDITIONS
How much are exchange fees?
Fees are calculated according to your exchanging amount in usd value:
Up to 50$ - fee 5%
50-100$ - fee 4%
100$ and above – fee 3%
additional 1% fee is added, if you want to receive your tip privately, without showing it in chat.
Fee is deducted from amount and showing in exchange form, you don't need to add any extra.
The fees are normal to be honest.
Similar fees are also charged almost when we made the withdrawal from the site.
Nevertheless it should depend how much quickly we will receive the amount through exchange.
Is it done automatically or processed manually?
I remember using Lupandina’s service 2 years back at stake.
