Laravel Cashier invoicePrice amount seems too big

[sts-ryan-holton]

Hi, I'm using the latest version of Laravel Cashier and am making simple charges with invoices. My Stripe account is based on GBP money format and I've set up 3 products in my Stripe test account each with their own one-time amount and price id. One for £10, one for £20 and another for £50.

When I make a single charge, I'm first getting the price of the item based on the stripe_id since I can't hard-code these values, so for example, the unit_amount returned to me for my £10 product is 1000, but when creating the charge, I'm charged for £10,000.

If I manually hard-code my invoicePrice second arg to 10 then I'm charged £100, what's going on here?
