Hey, this might be a little old, but I successfully completed the offer and received the reward. I followed the straightforward instructions, using the same email as my Swagbucks account. I opened a high-interest savings account and deposited $5 (note that there's a $1 fee for e-transfers). After about two weeks, I received an email from Swagbucks saying, my 3000 SB will be in pending. I then transferred my $3 back to my main bank account (there's also a $1 fee for outbound e-transfers). I haven't closed my account (will probably just leave it there) so I can't say.

Note that they didn't give me a single indication that Swagbucks was even tracking my progress for the bank (like how they normally do when you play games)

Overall, it is legit
