Supersonic speaker hire is having a massive discount sale on all their DJ hire packages with some as much as $100 cheaper! This special will be running through february all the way through march. Simply visit their website to take advantage of these ridiculous specials.
your link doesn't mention anything about $100 off so I assume this is your standard pricing unless the $200 basic pack comes down to $100 of course
P.s. you are the rep, shouldn't it be your website and not "their" ???
