I want to purchase 2pcs of items and it is remarked as BACK ORDER status.
I checked by live chat and they always say it takes 7-30days(depends on delivery). I actually asked 3days ago and they said again. When can I purchase 2pcs of it?
Please check and advise. info@e-jeiltech.com is my email address and I hope to get your answer ASAP.
