Shipping options

DHL: This is probably the best option to use as DHL accept parcels up to 17.00 oclock, this means that if you are from EU and place your order even hour before we close there is pretty good chance your parcel to be on your desktop next day in the morning. Good price and very fast service. Our own monitoring show that all parcels we ship with DHL usually are delivered in average 1-5 days worldwide (do not include customs delays), this means large portion of the shipments are delivered next day.
Online tracking is available at www.dhl.com.
TNT Express: This is good price and fast service but TNT accepts parcels until 15.00 o'clock so if your order arrives later the shipment will be next day. For most of the Europe destinations and parcels arrive next day or in 2-3 days, but not as fast as DHL for other parts of the world.
Online tracking is available at www.tnt.com.
Speedy: This is for shipments only for Bulgaria,Romania and Greece. Note that it may take three or more days.
Online tracking is available at www.speedy.com.
DPD: This is Road service very suitable for shipments with higher weight, usually arrives in any European destination for 1 week.
Online tracking is available at www.dpd.com.
Econt: Please note that this shipping option is available only for Bulgaria, they are express for next day delivery.
Online tracking is available at www.econt.com.
Shipment on account: If you have account with DHL, TNT we can ship on your account, but in this case when your order is ready to ship we will inform you and you have to organize the pickup with your transport company by yourself. If you want to use this shipping method please send us a email at support@tgrengineering.com with your account information.
