1. First, decide on the tech products you want to buy. You can do this by browsing the store's website or visiting the store in person to see what they have available.

2. Once you have decided on the products you want to buy, add them to your shopping cart or basket. This can usually be done by clicking on the product and selecting "add to cart" or "add to basket".

3. After you have added all the products you want to buy to your cart or basket, go to the checkout page. This is usually where you will be asked to enter your payment and shipping information.

4. On the checkout page, review the products in your cart or basket to make sure they are the ones you want to buy. You can usually remove items from your cart or basket at this stage if you need to.

5. After you have reviewed your cart or basket, enter your payment and shipping information. This will usually include your name, billing address, and credit card information.

6. Once you have entered all the necessary information, review it again to make sure everything is correct. If everything looks good, submit your order.

7. After you have submitted your order, you should receive a confirmation email or message from the store, along with details of your order and an estimated delivery date.

8. Keep an eye on your email or the store's website for updates on your order, and be sure to contact the store if you have any questions or concerns.
