Are there any Amex or chase offers to stack?
Unfortunately not. I use cardpointers.com paid membership which i paid $99 for lifetime membership, to save all offers to my account. Saves all offers across all accounts, When logged into chase or AmEx, it does its magic. takes about 20-30 seconds at most. I've been using the free scripts for the past while which i got from DoC or Reddit and it was slow like a turkey and took hours to save all offers across all logins for my AU on amex.
Then on my mobile phone with a quick search it shows 0 offers found, just the past offers that recently expired.
