I didn't get a chance to accept any items I bought inworld

You might see if the merchant has a re-delivery terminal at the store.  Otherwise, you will need to contact the merchant.  Be polite and explain the situation.  Not all merchants will re-deliver, especially if the items were no-copy, but it's worth a shot. Sometimes merchants will indicate on their profile if they prefer to be contacted via IM's or by NC's.

i 'd like to add a detail to the answer of Chantilly .

Mercants most likely will replace mod/no mod and copy/ no copy items, but not transferable items.

But keep in mind, because you logged yourself, some will frown a few times, and not sure they will redeliver manually.

Redelivery terminals can be your luck, those won't look at the reason you lost it.
