If you're only ever going to get (1) of these, I'd probably pay the price and be done with it. If however, you think you may get more daisy's, or aiders or anything else, make them yourself.
$14.50 for 50 feet of 1/8" amsteel plus shipping = (3) 8' daisy's
$3 = knitting needle to use as a fid
$1 = florist wire to use for the bury, free if you have thin gauge bailing wire laying around
Free = (1) playing card cut to length to use as a daisy eye measurement gauge
Total = About $25 for (3) completed 1/8" daisy's
