Then, the code should be like this?
OLD ITEMS
NEW ITEMS
EMAIL XXX@MAIL.COM
Will this make my old order become double in quantity?
You need to FIRST delete the OLD order items.
Say you've made the mistake of ordering this (using it as an example only) you must add the "0" to delete your items using the Bot. See below;
RETRO/STANDARD 0
RETRO/SPACE 0
Wait for the email response from the Bot to see if it's been changed.
If you now want to order (using this selection only as an example) a new item here it goes. See below;
NOIR/STANDARD
NOIR/SPACE
Again wait for the email response from the Bot to see if your order is correct.
It's then done. Please remember to always add your email address. It's safer to leave it in any order you want to add or amend. The bot will always deal with your own personal order via your email address and helps to make sure nothing is left out or lost during this procedure.
It also makes 7bit's life easier without having to respond to hundreds of emails on order re-fixing and alike.
