Data is delivered as zipped .csv files. Data is delivered by:
1. Physical delivery: compressed csv files stored in flash drive and delivered to your physical
2. Direct download: files can be downloaded directly from discountoptiondata.com after purchase at File Delivery
3. Google Drive delivery (super recommended): upon providing us your valid gmail address, files are automatically delivered instantaneously to your shared Google Drive. This is so hassle-free compared to the other options. The reason Google Drive is super recommended is in the extremely rare case of our servers going down at all, the chance of Google Drive going down is even way a LOT more unlikely. One note is your Google Drive most likely has 15 GBs available be default, but don't worry, since the files are shared from our Google Drive (more than 1 TBs), you don't have to worry about your Google Drive capacity.
