G: TLDR:
Your statement shows two separate Best Buy purchases, not the same charge twice.
Both were made on 02/02 at Best Buy Marketplace, each for $66.77, which totals $133.54 (plus the previous balance makes $148.12). This strongly suggests two items bought in one order that were processed as separate charges, not a duplicate billing.

What the statement actually shows

From your photo:

Transactions (02/02):

BESSTBUY MKT — $66.77
BEST BUY MKT — $66.77

Total: $133.54

The line below says:

Total transactions for Joyce M. Lillemon Boscher: $148.12

That number matches $66.77 + $66.77 plus a previous small balance or rounding adjustment.

Why two identical Best Buy charges happen

Best Buy often splits orders into separate charges when:

Two items were purchased in the same order
Each item may ship or process separately.
Marketplace items vs store inventory
Some items are billed independently.
Items shipped from different warehouses
Each shipment can create its own charge.

Charges with descriptors like “888-BESTBUY MN” simply mean the payment was processed through Best Buy’s billing system in Minnesota, not that it’s a different merchant. citeturn0search15

What this likely means in your case

Given the same date and identical amount, the most likely scenarios are:

Two identical items purchased
One item purchased twice
One order containing two items priced $66.77 each

Less likely (but possible):

A duplicate processing error.

Quick way to verify in 2 minutes

Ask your mother:

Did she buy two things around $60–70 each at Best Buy?
Check her Best Buy email receipts for that date.
Look in the BestBuy.com account order history.

Each item should appear as $66.77.

If it is a duplicate charge

Call Best Buy customer service:

1-888-237-8289

They can look up the transaction by:

last 4 digits of the card
date
amount

They can tell immediately whether it was:

two items
one item double-charged.

✅ My read of your statement:
There is no sign of a processing duplicate—it looks exactly like two separate purchases at the same price.

If you want, you can also send the first page of the statement (the part showing the actual items purchased). Sometimes it lists the product names, which would confirm instantly what the two $66.77 charges were.
