My parents do say thank you,if i buy them something but i know whom it comes out from the heart.

My father says thank you and bless me for very little thing i give to him e.g like complimentary card or drinks and he will make it look as if i bought him the world ,so yes i know he appreciate it to the deepest and from his heart.

My mother says thank you for a short time and u can feel it that she wants more even if i buy her the best car or house etc and mind u she will still cause me on top if i upset her and even beat me ontop if she gets the chance and compare me to other people that buys their mother more , ,so i know she didnt appreciate it that much .
