I had checked out the Atlanta Thread Company now renamed WaWak as recommended here and requested a catalog which they did send me about a month ago and have procrasinated ordering and glad I waited because this morning I received an email that there serger thread has an additional 20% off until the end of August making the 3000 yards Maxi-Lock spools only $1.59 instead of $1.99. All retail stores sell this same thread for $4.59 or higher depending where you look. So those of you who love Maxi-Lock may want to check this out before th end of this month and place your order.
