would you recommend I don't be greedy and just go for the coat on it's own?

Obviously claiming just the one Item attracts less attention.

That being said, the hoodie Is a low value Item, so I don't believe It will Impact your claim.
Ultimately It's your choice.

Also, if I use student discount on my order would that have any potential impact on my SE? (would be my friends code, I'm not a student)

That's fine - It's purely used for buying purposes, so there'd be no reason to affect your SE.

Okay thanks. I'm going to go for both items and claim DNA, with student discount the order value will be about £370. I'll be at home when it's being delivered so just wont open the door and keep an eye out the window, If the driver goes back to the van with my package I'll shout out to him to leave it at the door.

Hopefully I can get a rep that issues an instant refund, if not I will try calling instead, If I an investigation is opened and I am asked to fill out a PR I will just say the item has shown up and do a legit return but use the method I spoke of earlier in the thread where the coat will be replaced with an old one, I know you weren't sure if that still worked but even if it doesn't I can just say sorry I wasn't home and told my mum to send back my coat but she must of packaged the wrong one, then legit the coat as well and take my L, but hopefully it doesn't come to that.

Do you see any issues with this plan?

Why don't you want to file a PR?
