Hi, my sister has not long received a 13" MBP, however is now reconsidering and looking to get a refurbished 15" MBP. She has the RMA number, etc and the courier will call either tomorrow or the day after, the question is how long will the process take from collecting the 13" to crediting her account? as she is afraid the refurb 15" will have been bought by then. I've told her that the times they quote on the site are usually slightly exaggerated to cover themselves. Having never needed to use Apple returns myself, I have no experience of how efficient they are so I thought I'd ask here. Note that this is the Apple UK online store. Any info or experiences on their returns process will be greatly appreciated, cheers.
