Do you ever not buy something you can afford because doing it would make you feel like a sucker?

So today I called my pharmacy to find out what happened to my order of Dexilant, a stomach medication I have used before for acid reflux with good results. The pharmacy told me that my insurance company refused to cover it, but they would sell me 90 pills for $ 900 out of pocket. I declined, since even though I can easily afford it, buying it would make me feel like a chump and a victim at that price - and it isn't cheaper elsewhere. Instead, I bought the same amount of Omeprazole for 50 bucks - it too will work for me but not as well.

Have you too had an experience like this where you didn't buy something you could afford because doing so would make you feel terrible?

Good news - My insurance company just decided to authorize the drug after all - for awhile anyway.
