Raw and new poem

An Unplanned Trip to the Thrift Store   
 
I awaken early, remembering
the smallness of my granddaughter’s coat.
 
Later, a woman in the post office greets me,
Chilly outside, isn’t it? I agree.
 
Next I’m stuck on one thought
as my feet hurry toward the car.
 
I set off for the thrift store,
the best place in town for bargains.
 
On opening the door, I look around.
So, now what? I head for the clerk.
 
A few blazers in here, but the warm coats
are outside on the porch.
 
I shop in the cold—brown coats, gray coats.
Then I spot the hot pink stadium coat—
 
her favorite color, her exact size.
I check and recheck the secondhand coat.
 
Suddenly, I feel my heart growing happy
like smoke rising from a chimney.
 
Back inside, I smile, stand in line,
then fumble in my purse for ten dollars.
 
I look at the cashier. She says, You can use
a card, but then the coat will cost $12.25.
 
So, okay.
I don’t believe in coincidences anyway.

Pat,

I get bogged down in the details.  (Your title offers so much)  How many of these details are for the writer and necessary for the reader?

Is the point of the poem 12.25 is the date of Christmas?  

Does the cashier ask you about a card because the coat is marked $10 and yet your ten doesn't cover the cost?

Oh my goodness.  I see the Christmas date now.  $12.25.  I was totally oblivious.
And I had stood in line, assuming I had $10.00.  I did not.  I had $7.00.  
The cashier saw the problem... she seemed to wish I'd find more money and not use the option of a card.
She even said, "Do you or your husband have a military discount?" 
Nope. One surprise after another.
The price of the coat would be more if she had to process it via a card...I finally bought it via a Visa card, but it cost over $12 which was still a bargain.
Too many lines, too many details.  It's as I lived it.  I agree:  readers don't need so much detail.  
Thank you!  Good feedback info for me.

This is how it worked out for today.  I thought about Billy Adams saying, "So what???"    
So, a revision.   

A Way Opens, Regardless
 
I awaken early, remembering
my granddaughter’s need for a coat.
 
Do not ask if I’m stuck on one thought
as my feet hurry toward the car.
 
I set off for the best place in town
to bargain-shop.
 
On opening the shop’s door, I look around.
So, now what? I head for a clerk.
 
A few blazers in here, but the warm coats
are outside on the porch.
 
Do not ask how long to push past brown coats, gray coats
before spotting the hot pink stadium coat—
 
her favorite color, exact size for only ten dollars!
I triple check the secondhand coat.
 
Suddenly, my heart grows happy
like smoke rising from a chimney.
 
Do not ask, do not ask. I stand in line
and fumble in my purse to find seven dollars.
 
The cashier with a quick heart says, 
Sure, you can use a card, but there's a charge-- 


that way it’ll almost cost you 13 dollars.
Okay, I’m calling it a tiny miracle anyway.
