I got my brother in the US to buy me the ARRIS Fleece Heated Vest for Men 7.4V Electric Warm Vest 8 Heating Panels which was on sale for $79.99 1 week ago. 4 days after the order was confirmed they cancelled the order. My brother emailed them to ask why the order was cancelled and they told him that they could not find proper international courier service to ship the item to Australia. This response was from Cherish. I think they cancelled the order because now the sale price for this item is $99.99. Dodgy business. stay away.
