My imports are on a D/A 30 Days sights term. The first 50% for the goods has been paid up. The D/A is for the remaining amount balance of 50%. However about 50% of the goods turn out defective. Are there any recourse for me? I'm sure my supplier will not agree to a 50% discount but I really shouldn't be bearing the cost of the crap they sent over. Any advise? Thanks.
