Where can I buy battery powered led fairy lights in stores in Canada?

I'm planning on using battery powered led fairy lights or any sort of light up strings powered by a battery pack for a project (http://www.amazon.com/gp/product/B003J99JW4/ref=ox_sc_act_title_1?ie=UTF8&m=AW2PJ3BXEXRVP)-those are fantastic too, however the problem is that I need them A.S.A.P! (Before next thursday, july 14). Does anyone know where I can purchase probably not larger than 10 ft sting of lights for a reasonable price? Like under or around $25?
