help, problem with charges from a site (more than secure order said)

[misdee]

i ordered some clothes recently from a online store. the secure order said £38, recieved the goods and invoice today, and says £65. have checked my initial order and notice they hadnt put the correct price for 3 t-shirts, but have been charge the correct price on the invoice (t0shirts actually went thro for free, but have been charged £10 for each)

Email them and ask how to return the shirts postage-free. Hopefully they'll say to keep them and only pay the 38 GBP.

well i've called them to query it. i saved the secure order conirmation.
