Nice catch...
I'd say you did alright on that one, considering it's complete and in good shape. While I have seen--and bought--several Kirbys at thrift stores with complete accessory kits, but I've never seen an Electrolux--canister or upright--that way. They usually come with maybe just the hose, maybe a wand and power nozzle or flippy floor tool. Accumulating those other pieces adds up quickly. Paying a bit more for the complete package is always worth it. And hey, if you decide that machine isn't to your liking, you can always eBay it for a tidy profit. Definite score and definitely nice of the lady at the store to point it out to you.
