Random 1$ charges

[etley]

Why am I seeing 1$ charges after every purchase I make? I order an item for 34$ and then there’s an additional 1$ charge from eBay.

Some debit cards charge a $1 fee for certain kinds of transactions. Make sure you are not using such a card to pay for your purchases.

Many credit/debit cards will put a temporary $1 charge to your card to prove it is valid.  The charge will usually go away in several days.
