I think you'll find it's exactly the way to steal business from a competitor ! You don't need to beat it by a huge margin but enough to sway the deal ! as I've said before to others, discounting to sell a product to make 20% of something is better than not selling the product and getting 20% of nothing ! Consumers need an incentive and all the little numbers add up to bigger ones ! Ps, I was curious and emailed HDI and got a broken Engrish repry from Hung Kung ! Q, Are these a direct replacement and no cutting chopping etc ? A, Hi Sir, Thanks for your message. Yes, they are direct replacement, please let us know your email address, we can see you the installation. Hi Sir, We just sent the email to you. Please check. If you have any enquire, please don't hesitate to let us know. Still didnt reply to exact question in regards to cutting/chopping.
