I am helping a family member with a large purchase (10k). I was looking for advice on the best way to capitalize on making this large purchase. Any advice would be great.
The cards offering 5% are generally in specific category and only a certain dollar amount in purchases qualify for that high cashback. They're good if you can take advantage of them but the threshold for these offers is way under $10k
There are a bunch of other credit cards out, you'll have to look into/research them on your own and see what you want (cashback/flyer points/etc).
