Got to do a little head to head comparison this week. This is from the
West Marine store in Corpus Christi vs. Defender's online prices.

32 oz. 303 fabric protector: West - $27, Defender $32. This was a
surprise.
18 g duplex wire, Ancor: West - $75, Defender $43.
3M metal restorer and polish, 16 oz. tub: West - $28, Defender $19.

Also, add 8.25% sales tax to the above if purchased locally. Very
advantageous to shop online, I'd say. West will usually price match, if
you bring in a web price.
