Cathy, unfortunately, you really must watch purchasing rodents from pet stores. I know here in Louisiana, I have come across many animals that I would have loved to adopt, but upon further inspection, many were teeming with mites, lice, wet tail, upper respiratory infections, cancers, and who knows what else.
This is in part due to the fact that all the animals in most pet stores are housed in one main unit, which is seperated only by plastic or glass. All the air and ventilation still passes through each tank, so whatever one tank may have, the other is likely to catch it.
I, too, feel unfortunate that you have to bring Blondie back, but if you are unable to endure another round of vet bills, it may be the only solution.
When you pick up your new little hamster, just check him over very well before even leaving Petsmart.
Here are some signs and symptoms you should look for:
Make sure he is active and alert. Make sure his eyes are bright, and his/her coat is full and vibrant, not dull or have any missing patches, thin spots, or dull spots. Also check to make sure he/she is not scratching or itching.
When they let you hold the hamster, check its rump. Make sure there is no feces caked to it, as that's an indication of Wet Tail (number one symptom is severe diarrea), which is very deadly. Hold it for a minute and make sure you see that it is breathing okay; no wheezing, gasping, shortness of breath, and no crackles in his/her chest.
Most importantly, check all out the hamsters in that same tank very well. Make sure none of them are presenting with any of the symptoms that I listed above. If you need to, ask to hold each one in the tank that he/she is housed with, so that you can thoroughly inspect them. If they are sick, yours will most likely be too, even if he/she is not presenting symptoms yet.
If all this checks out fine, you should, hopefully, be bringing home a healthy little addition to your family.
Good luck, I truly hope all this helps, and that your new little addition to your family will be happy and HEALTHY!

Always check with your vet for any symptoms your pet exhibits.
