I got both a Coconut & Rum Emulsion (4 oz) at Ross yesterday for $2.99 each. It's not a lot cheaper, but if you're like me and have to order everything online due to not having a cake supply store near by then...
I bought the same thing
They also had Lorann's vanilla, but they wanted $5.99 for the bottle.
Polkadot, do you have a Hobby Lobby near you? They carry Lorann emulsions, but not usually rum or coconut.
HomeGoods (Marshalls) often has gourmet vanillas and things too...
I saw the Vanilla too, but didn't think that was such a good deal. I've found good vanilla there before for $3.99.
The closest HL, Michael's, etc are an hour away and I'm not hugely impressed with their selection either, so I order alot of stuff online.
