I sold something through a FB page, and the buyer wanted to pay through PayPal. I organised this and money went into my PayPal account. I then transferred money from PayPal to my bank account but it says it will take 3-5 days to go through.

Should i send off the item today, or wait until i receive the money?

If i had gone through bank transfer, i would have waited for the money and then had money for postage. Are there different rules if you pay through PayPal?
