I am sorry if you are not successful in buying something in one of my restocks. I have some tips for success, (but they are not guarantees):
Create an account on my website
Save your shipping info ahead of time
Subscribe to my email list to learn the date/time of the restocks
Set alarms on your phone, and log in with time to spare
Refresh your page at the time of the restock until you are able to add items to your cart
Have your payment info ready to go (accepted forms of payment are at the bottom of my page, but I suggest you consider options like Google Pay, Apple Pay, or PayPal for speedy checkout).
If ordering multiple items, check out one item at a time. I will ship duplicate orders together where safe, and refund any applicable shipping overages.
These are merely suggestions for increased success, and do not guarantee a successful checkout. Shopping for multiple items during a restock may also result in an item in your cart selling out. (Items added to your cart are NOT reserved. This is a feature not offered by Shopify.)
