Buying simple wedding invitations is a straightforward process. Here are the steps to follow:

1. Set a Budget: Determine how much you're willing to spend on wedding invitations. This will help narrow down your options and guide your decision-making process.
2. Decide on the Design: Choose a simple and minimalist design for your wedding invitations. This could include clean lines, minimal graphics, and understated typography. Consider the overall aesthetic of your wedding and select an invitation design that complements it.
3. Research Online Retailers: Look for online retailers that offer a variety of simple wedding invitation designs within your budget. Websites like Minted, Zazzle, Basic Invite, and Etsy are popular options for purchasing wedding invitations online.
4. Browse Designs: Browse through the selection of simple wedding invitation designs available on each retailer's website. Take note of designs that appeal to you and fit your vision for your wedding.
5. Customize Your Invitations: Once you've found a design you like, use the customization tools provided by the retailer to personalize the invitations to your liking. This may include adding your names, wedding date, venue details, and any other relevant information.
6. Review and Proofread: Before finalizing your order, carefully review the details of your wedding invitations to ensure accuracy. Double-check names, dates, times, and venue information for any errors or typos. It's a good idea to have someone else review the invitations as well to catch any mistakes you may have missed.
7. Place Your Order: Once you're satisfied with the design and details of your wedding invitations, proceed to checkout and place your order. Be sure to provide the retailer with any necessary information for printing and shipping.
8. Choose Shipping Options: Select a shipping option that works best for your timeline and budget. Keep in mind any additional costs associated with expedited shipping if you need your invitations to arrive quickly.
9. Track Your Order: After placing your order, keep an eye on its progress by tracking the shipment online. This will ensure that you receive your wedding invitations in a timely manner.
10. Address and Mail Your Invitations: Once you've received your wedding invitations, address the envelopes and send them out to your guests. Be sure to allow enough time for guests to receive the invitations and RSVP before your wedding date.

By following these steps, you can easily purchase simple wedding invitations that reflect your style and set the tone for your special day.
