If I may ask have you tried calling them? Suppliers tend to have backlogs of emails specially since it is almost Christmas. They might be getting a lot of enquiries this time of the year as retailers and consumers are online hunting for great deals. Giving them a call is a fast and effective way of contacting them. Just note that like other businesses, suppliers also close at night and during weekends so if you give them a call, make sure to do so during office hours.
If you sent them an email using the email address on their SaleHoo Listing, you can try to send them an email again but this time, use their online enquiry form:Link hidden: Login to view
