Salfcl, did you get the flowers delivered to a US or a Canadian address? I haven't been able to figure out how to register for aadvantage shopping without a US address/zip code - how did you manage?
Redhead, even the minimum amount of miles to purchase has a $30 transaction fee and costs another $40 or so plus taxes. I'm trying to avoid spending that kind of money. But I'll keep it in mind as a last resort.
