Ukuthumela ngomkhumbi	Isikhathi sokulethwa	Ezingxenyeni zesitoko, ama-oda alinganiselwa ukuthi azothunyelwa ngezinsuku ezi-3. Sithumela ama-oda kanye ngosuku cishe ngo-5pm ngaphandle kwangeSonto. Uma isithunyelwe, isikhathi sokulethwa esilinganiselwe sincike ezincwadini ezingezansi ozikhethile. I-DHL Express, izinsuku zebhizinisi ezi-3-7 ze- DHL eCommerce, izinsuku zebhizinisi eziyi-12-22 I- FedEx International Priority, izinsuku zebhizinisi ezi-3-7 i-EMS, izinsuku zebhizinisi eziyi-10-15 Imeyili Yomoya Ebhalisiwe, izinsuku zebhizinisi eziyi-15-30
	Amanani okuthumela	Amanani okuthumela e-oda lakho angatholakala enqoleni yokuthenga.
	Inketho yokuthumela	Sihlinzeka nge-DHL, i-FedEx, i-UPS, i-EMS, i-SF Express, kanye nokuthunyelwa kwe-Air Mail okubhalisiwe kwamanye amazwe.
	Ukulandelela ngomkhumbi	Sizokwazisa nge-imeyili ngenombolo yokulandelela uma i-oda selithunyelwe. Ungathola futhi inombolo yokulandelela emlandweni we-oda.

Iyabuya / Iwaranti	Iyabuya	Ukubuyisela ngokuvamile kuyamukelwa uma sekuqediwe phakathi kwezinsuku ezingu-30 kusukela ngedethi yokuthunyelwa, sicela uxhumane nesevisi yamakhasimende ukuze uthole ukugunyazwa kokubuyisela. Izingxenye kufanele zingasetshenziswa futhi emaphaketheni okuqala. Ikhasimende kufanele lilawule ukuthunyelwa.
Iyabuya / Iwaranti	Iwaranti	Konke okuthengiwe kuza nenqubomgomo yokubuyisela imali yezinsuku ezingu-30, kanye newaranti yezinsuku ezingu-90 ngokumelene nanoma yiziphi izinkinga zokukhiqiza. Lesi siqinisekiso ngeke sisebenze kunoma iyiphi into lapho iphutha lidalwe ukuhlangana kwamakhasimende okungafanele, ukwehluleka kwekhasimende ukulandela imiyalelo, ukuguqulwa komkhiqizo, ubudedengu noma ukusebenza okungafanele.
