First time mommy: What to buy?

Hey ladies, I am a first time mommy to be & I chose not to have a baby shower. Instead husband and I chose to save money to buy stuff ourselves. I'm going this weekend with my mother and sister to get most necessities (my husband will be out of town). They will be helping me buy some stuff as well. I am less than 2 months from my due date and would like to buy the "important/main" stuff while husband is gone. What should I be buying? Any recommended stores? Anything from the smallest thing to the obvious big stuff like strollers, cribs, etc. I'd like to get everyone's input. Ps. I would like to get as many things at an affordable price!
