Hello forum,
I write in a bit of a panic (so please forgive any poor typing!)
I came home from work roughly an hour ago to find my beloved Oranda fish, Chips, floating on her side at the top of her tank. My immediate thought was that she was dead, but after some gentle massaging she slowly moved a fin so I quickly transferred her into a tupperware of tap water.
After reading much advice online I decided to try a salt bath, and filled our family bath tub with water, dissolved some sea salt in it, and put Chips in there to see if that would help. I guided her through the water, gently massaging her underbelly (as I read online). After some time in her salty bath, Chips has started to perk up slightly. She is making every effort to move her fins (though she clearly doesn't have much energy and isn't getting very far!), and is occasionally leaning to one side or doing backward rolls in the water. She also seems unable to turn, once she reaches one end of the bath she simply keeps swimming forward into the side! At the moment she is moving her fins to little avail, a sort of swimming on the spot. Sometimes she doesn't move at all.
I have also noticed that she has white spots on her gills and face. I have treated her for white spot before and thought she was better, but it seems to be back with a vengeance.
Judging from what I have read online, it would also seem she is suffering from a swim bladder problem.
As it is a Sunday evening, there is very little I can do by way of purchasing the necessary treatments. I don't know what she needs, and really need some advice to help her pull through until the morning... And what best to buy her then when I'm at the store at 9am!
Any help would be MUCH appreciated, I'm at a total loss here and really just don't know what to do for the best. Please help!

The fish probably got badly shocked when you threw her into a tupperware with tap water :/ TAP WATER contains CHLORINE that burns the fish. You soon after put her into a bath tub, bath tubs have traces of soaps and harsh cleaning chemicals which will burn the fish worse than the chlorine will. (Hence most people keep all their tank buckets separate from everything else to avoid contact with chemicals). So don't ever do this again, if possible, you should never take your fish out of her tank, especially if she's showing symptoms of discomfort or illness.
Next, your oranda has white spots on the head, this means that the headgrowth is growing, there is NO ICH nowhere to be found, and overtreating the fish, which I noticed you already did once before, is doing far more harm than good :/

Now, take it easy, put the oranda back in the tank, and buy water conditioner, that's the first thing you need to do. By now she may basically be destroyed by the chlorine if you have never used a water treatment before. Water conditioners remove all the harmful chemicals from tap water, and help the fish stay healthy. Without this, their internal organs will be broken down by the chlorine and harmful metals.

How big is your tank and for how long did you have it set up? Are you changing the water? How much, how often?
That's the next thing, you need to provide a 20 gallon (80 liters) tank. 20 gallons may sound like a lot, but an oranda may end up being 12 inches long if it's cared for properly The tank also needs to be cycled, Cycling is the process where ammonia is being neutralized by beneficial bacteria called nitrobacter. Ammonia is another menace for goldfish, in small concentrations it can be lethal, and that's why cycling is so important. You need to buy a water test kit for pH, ammonia, nitrite and nitrate, like Goldiegirl said. Otherwise, everything's covered. I do hope your fish will make it Fingers crossed!
