Honestly, I'm not sure if DNA will work well. You could do a FTID instead since it makes it more legitimate, but since it's such a large ticket item, I think it may best if you avoided DNA. Then again, I'm fairly new to SE, but intuition lies with avoiding DNA for items > 200.
For OTP, you can reach out to customer support and look like a concerned customer wondering about the logistics of delivery of such a big ticket item.
Simply replacing the item with a similar item of similar weight could help legitimize any returns you may perform.
Hopefully that's of help, good luck!
