I placed a big order last week during the spend $100 get $50 in August promo. Since then, the price of the t-shirts I ordered have went down. Per their price adjustment policy, I am owed around $15. Should I ask for an adjustment and risk not getting the $50 or should I just forget about the $15? Thanks! BTW the logo shirts are now $3.99 for adults & kids + $15/$60 purchase!
