I have been using Toppgo services for more than a year and I'm absolutely satisfied with it. It helps me to save much money on purchases + I can buy specific items which are not selling on international markets. To save more, it's better to buy several things at once rather than each thing separatelly. Everything is well-organised, using this service is really easy (just put the link of the item which you want to buy and they'll do all the work). Prices for the service are moderate.
Surprised by the quality and speed of work. Thank you very much!
