Quoted from vid1900:Menards has them, and in the past, has them for $7.99 on Black Friday.
Amazon has them (but you can't see if they are cloudy until you get them). After you return 2 to Amazon, they wont replace them any longer, and will only refund you.
Spencer (the weird store at the mall) has them, and some designs are "spencer exclusive"
Always check inside the box. If it's at all cloudy - DON'T BUY [quoted image]
Also check Home Depot, mine carries a couple different ones. Spencers is good if there is one near you, mine closed a couple of years ago.
