Well, that didn't work out so Well

Here's a quick summary of how the offer on the condo. went

Friday morning - 7:00 am
We asked the realtor via email to present our offer that day to the seller.
Finally, at around 4:00 pm, we received the Earnest Money Contract via email. (So much for presenting the offer the same day, I guess).
Everything is done through the internet, so no hard copy and no wet signature.
We reviewed it, and asked that she re-word some items.

Saturday - 8:00 am

Realtor called and said she would make the changes we requested and present to seller, through email.
We asked for a response from the seller by 5:00 pm.

Sunday - 10:00 pm

Nothing. No email. No phone call. No communication. No reply.

Monday - 5:30 am
I checked my email and see that the realtor had forwarded us an email response from the seller. He replied to her at 7:08 pm., and she forward to us at 10:18 pm. (She may want to pick up the pace a little).
Problems with the Earnest Money Agreement. The Realtor should have used the contract for a condominium and instead used a single family home contract. She had the incorrect financing method indicated. (which we questioned her about and was told 'Oh, it doesn't matter, no need to change....Hmmm...guess she was wrong.)
Seller refuses to pay Home Warranty. (We (Henry and I) wanted that removed, because we don't care, but the realtor advise we leave it in).
Apparently, we are to receive the CC&R's on the condo. building, and have not.
He did agree to pay off the special assessment...that was good news.
He upped the sales price by a mere $980 and refused to pay any closing costs.

Realtors email also said she would call us THIS morning to discuss Seller's counter. - It is now 2:45 pm. and she has not called or emailed.  Think it's time to wash our hands of the realtor. Don't know about the seller at this point. Heck, don't even know about the condo. anymore.
First rule in sales, whether it be selling cars, real estate or furniture; when you've got a buyer, ready to spend money and actually buy....you never, never, never give them time to rethink their decision (especially an entire weekend) without finalizing the deal.  She did exactly that, so I'm afraid she just lost out on a sale.
You snooze, you lose. Isn't that how the saying goes?
