As others have stated; stock UP and UP on diapers.
Either get the cloth (to save money and experience first hand...:evil

or use the throw aways.
You can not get to much of either. For the throw-aways, figure going through close to 10/day for the first 6 months and down to 5/day for the next year afterwards.
If otherwords; stock up while they are on sale; You can always return them to the store for credit against a larger size. the packages are numbers by age group/size for easier reference.
Unless you are fashionable; in the beginning, the generics will suffice.
Get plenty of baby lotion and also stock up on baby wipes. Get 3 dispenser packs and by plenty of bulk refills. Keep one dispenser pack in the diaper bag, one in the living area and one in the babys bedroom area.
Delivery clothing and furniture will be useful in advance.
Baby bottles, brushes, nipples can be purchased in advance if desired; not critical.
Formula (if to be used) can be purchased in bulk.
Also, get a wireless baby monitoring set. Great peace of mind.
As much as you can get done in the next 3-4 months, the better. After the baby arrives, you will have less time to get all these additional items.
Keep stock of your supplies; DO NOT run out; get the replacements in advance.
