Per my latest phone call to Discover 800-347-7000 this thread needs a wiki update. Loaded $1K on 8/29. Loaded $500 today. Second load failed. Called and was told '2 days ago' the load limit was reduced to $500 per 24 hours. If anyone else has different information, I would love to hear it. Very disappointing.

hmmm, I had a fail today on a second (500) load, this may be the reason

Well, it may be, but it may not be. Today I looked at Discover's website and found clearly stated "$1K limit per 24 hours"
So, I called the same number, got a different agent and she asserted that $1K remains the limit, nothing changed.
I will try again Thur and meanwhile I assume nothing changed. But it is certainly concerning that you also met with a successful $500 load followed by a failed load!
My second attempt to load $500 was using the same funding means that worked for the first load that was successful. This is the first time (out of many) that I have had a failure on the second load.

looks like I had some other issue going on yesterday, tried again today <24hrs after yesterdays Load#1 and it went thru

the "deposit account agreement" has not changed since April/May

I did $499x2 back to back on 8/28

I did my very first 2 loads to discover at $400 each for a total of $800 yesterday. I did first load for $400 because I saw your post about possible $500 daily limit. Then a few hours later I thought to try another load see if it works and it worked for another $400. But I thought maybe discover has life load limit for each member. Since I never loaded money to discover before yesterday they might allow the 1k limit(?)

It is $1K every 24 hours, so make certain that it has been at least 24 hours, as well as no more than $10K in a 30 day period.

Did $400 then did $500 a few hours later so limit probably still 1k every 24 hours.

After a few months off, every WM in my area. I'm assuming this is not specific to just Discover loading. I still can only load 1 $499 VGC/MC. Any 2nd swipe/transaction with another VGC/MC card will lock up and require replacement. I can finish a 1k load with say $499 VGC/MC + $501 Cash back debit card.

I was successful 2x$500 back to back on Thursday (different Walmart), but for now I'm just going to ignore that it happened once and assume nothing changed. I certainly felt the cashier was competent and didn't screw it up, but actually I have no idea why I got the one failure 6 days ago and probably never will.

Staff at 2 WMs near me said that I couldn't load with gift card. They didn't even let me try. Am I out of my luck?

all depends on the cashier and location. Keep trying.

DP: I loaded $1K in one transaction yesterday using a bank debit

Was the net result a bank to bank transfer?
