As always, excellent advice! ^^^^
I typically try not to do more than $1500 in Disney gift cards at one time and I also get other items as well. I've never had a problem and I also don't comment or say anything. I've easily spent almost $2000 on my Target Debit card but obviously had that in my checking and I think it's helped that I've gradually built up this limit and since day one, never had an issue.
A friend of mine tried to get $1500 with her Target Debit card and she also had the funds available, however it was declined and she ended up going to c/s and they did them in batches but it drew a lot of attention and questions but they did help her.
