From Ear Plug Station's promo email:
"HALF PRICE … on ALL Macks products for a limited time. … Enter code MACKSONSALE at check out to collect your discount…"
this range has product to suit kids, snore sufferers, some workshop and tool use, swimming, flying, etc…
I'm bothering to post this because I've bought several full audio frequency limiting earplugs for concert use and this companies service was impeccable.
