Looking to buy a microwave, bike, study table and study chair

Hi, I just joined Stanford and moved in to CA. I am looking to buy a microwave (price preferred below 15$), a study table (price preferred below 20$), a study chair (price preferred 10-15$), a bike suitable for 5'3'' female (price below 30$). I do not have a car, but if you can deliver, that would be super-helpful!! I am in Mountain View. Please email to maitreeg@stanford.edu if you have any leads. Thank you in advance.
